Look at the magnetic field under a ferrocell. It will explain a lot.
I do a lot of welding for a living. It seems to me that when the magnet was put on the magnetizing coil, there might have been a spark or contact that made those small spots have an opposite polarity. I say this because the pattern looks just like an electric spark pattern on the metal. I see those often in welding. Well at least that is my idea of it, take care :)
Thanks - it does look like an electric spark pattern but remember an electric welder can't strike an arc around a strong magnetic field.
@@SuperMagnetMan I think it might be red hot welding spatter that was bouncing on the surface. Biggest dots are darker as the metal was hoter and spaces are wider as it was less magnetic.
I had the same theory, I too am a welder and thought it could be from the initial magnetisation procedure. That is amazing, I can't wait to see what people do with magnets in the future as we are only in the baby stages of experimenting with them so far.
By the looks of it, it seems that maybe a ball bearing was attracted to the magnet and then bounced multiple times as it impacted, as the increasing frequency of the spots diminish in size as well. This is probably because the bounces had decreasing impact force on the magnet. I know that Sharp hits on a magnet can realign the domains, so I’m going under the assumption that this was a ball bearing hit on the surface
It comes to me as no surprise when the suspended filings do nothing near the surface of the magnet until an anomaly is reached. If the field is very uniform there is virtually no magnetic force. Magnetic force is proportional to the change in magnetic flux through space. If the field isn't changing much over space, there may as well be no field at all when it comes to forces on objects like these filings. Now at the spots, the situation is deviant from the norm and thus so is the magnetic field generated at those spots. Near such points there is a change in flux and consequently a force on the suspended filings. At those damaged points the field is weaker and so the filings are attracted to the surrounding where the field is stronger so you get empty circles like we see in this video. No mystery to me about this, just a surface damaged magnet that otherwise is just fine for all practical purposes.
Impurities in the material that the magnet was originally made of? I was a heavy metal sawyer for years and I would see this type of flaws in steel, brass and bronze just to name a few. I hope this helps
a high heat source weakened sports on the magnet like a high power laser or voltage maybe. OR
The the magnet has impurities or not mixed well on that spot underneath the coating. Which as you notice the metal is attracted around the dots and not at the center since the center has the impurities and thus the weaker field and the edges has collects most of the metal.
That is my guess.
Possible arc marks from when magnetization process. Where those arc marks are maybe the magnet is demagnetized there and the iron fillings are drawn to the field lines surrounding those marks. Possible test is to make another arc mark using dc current I would try both polarity to see if that makes a difference.
When I received the magnet 5 or 6 years ago it did not have these dots on it and so there is something that must have happened here but I can't imagine what it would be.:)
No dots when new? Now that's very intriguing.
Magnetic fields are dynamic rather than static, I believe, due to the alignment of electron spins or coherent electron currents. Did you store the magnet near other magnets or near energized electrical circuits? It is very intriguing that these spots appeared after you got the magnets, so it could not have been due to manufacturing defects, etc. These new domains somehow generated themselves due to the dynamic action of magnetic fields which originate in electron spins. That's my best guess right now.
i don't know anything about magnets but the pattern looks like a logarithmic spiral
maybe you know more than you realize.
Theres another straight it seems at about 90 deg to the swirl that dont clear the field
It almost looks ilke the magnet was/is getting damaged either from physical damage or over time from the magnetic "radiation". aside from that the dots are in a line that looks VERY similar to centrifugal divergent lines of magnetism.
I think it looks like the golden ratio 😉
Very interesting and some great theories below. I'll be thinking some more about it. Thanks for showing this.
Bad mixture when making the powder for the magnet. So there are several magnetic fields in the magnet. You can see the same circles on the magnet it self
Its simple, the areas that have a irregular look have less magnet force on the iron because the surface is not even, therefore the areas that are not uneven are closer to the iron on a microscopic level, thus those areas have more magnetic attraction then the irregular areas. Its the same reason why you don't have a perfect flat picture of the iron shavings on the magnet, because the magnet will never be perfectly magnetized throughout itself. Just like how areas on the Planet that are further away from the center of the Earth, such as the top of Mount Everest has less oxygen to breath because all the oxygen is trying to reach the center of the earth. Therefore being more dense near the ground. Its on 1/1000th of an inch difference that you are seeing because you are using iron powder.

QUAKES DURING AUGUST 2019:
10 quakes above magnitude 6
129 quakes between magnitude 5 and 6
807 quakes between magnitude 4 and 5
2364 quakes between magnitude 3 and 4
5307 quakes between magnitude 2 and 3
18645 quakes below magnitude 2 that people normally don't feel.
These look like points of physical abuse. I bet some object impacted the surface and bounced a few times while sweeping by. At the points of impact the shock may have freed the material to assume a different magnetic domain direction and while in such "freedom" they assumed a reverse direction like what happens if you try to align 3 bar magnets in parallel and find the middle one trying to flip around opposite the other ones. The shock "breaks" the magnets into close-by parallel magnets and those (even dust) that are free to reverse do so. At such points you would expect anomalous magnetic fields. That's my call, anyway, if I had to guess. :-)
I think the answer is pretty simple. There's regions in the magnet that are materials that have less ability to take on a magnetic field or perhaps have their field turned to some other direction. They are surrounded by proper magnetic material with all the same orientation. All that you are seeing is the iron powder being attracted to the borders between the 2 types of materials or 2 magnetic orientations.
I noticed the spots are larger on the right, and lessen in size and distance as they reiterate going leftward. I also notice the spots curve up and circle back downwards. However, they don't seem to have the same effect, unless it's very subtle. I'd look at the filings under the microscope, while they are on the magnet of course. The pattern seems like a clue, noting the reduction in amplitude/power of the negating effect along the arc. Like an unfocused, pulsing laser, lit the surface, during a curved movement towards or away from the beam. That's if a laser could do that. It also looks like a bouncing pattern, and the looping could be from the bouncing object being influenced by the field. Very interesting though, until you find out, then it will probably seem plainly simple.
My guess is oxidation below the nickel coat or impurities in the nickel itself focusing the field to higher saturation in specific areas. It’s the same thing as putting a small steel disk on the surface of large permanent magnet. The field will be altered and your nanoparticles will show it if saturated within the effected area.
This would be my assumption also it needed time to form before showing up 5yrs later...
Oxidation due to impurities in the metal cause the spots to appear over time, those spots cause fluctuations in the otherwise homogeneous field. When you put the cup down over those spots you induce eddy currents that push the filings away, and then when you moved it around, same thing happens.
OK at first blush, you magnetize particles or sync them at 1st touchdown, and after moving it the particles realign but are affected by the magnetic field lines (the torus) as synced at 1st touch. I am intuiting that the low distance pickup height to move the cup is significant?
Also, did you do the experiment with find cup of filings? 30 included diamagnetism in history of tubes of Force, explaining magnetism in a way similar to hydrostatics. We should expect to see vortices
The dark spots looked like they were deposits ( looks thicker than the rest of the surface) of some sort that act like “shielding” materials at those points. That is perhaps why the spots in the alcohol are clear because there were no attraction there and, the iron particles tend to accumulate on the edges. Impurities on the metal before subjecting to the magnetizing process could have caused them.
Due to the surface defect which i guess probably caused by welding spots, those regions have got demagnetized due to crossing their Curie temp. So the iron filings eliminate those areas.
it is a simple manufacturing defect - during the manufacturing process of the ferromagnetic material - when the molten ferro metal/alloy was cooling/solidifying some non-ferro material dropped in and solidified; and when this finished ferro material was magnetized; it did magnetize the ferrous material as expected and non-ferro was NOT magnetized; so when you bring the iron filing over those spots they simply do not attract them showing an empty space.(edges of ferrous material has higher field strength .. so a ring is formed) ... i spoke like a professor... lol ... well that is my informed guess.
I think it's the light that is doing it. Try this with different colors of lasers shining through the solution to see where the laser breaks. Another thing you could try to prove this is to paint the spots different colors or paint different patterns on the magnet to see how it affects the magnetism.
It's definitely strange, I'm stumped. 🤔
The anomalies are opposite to the pole. Say You are facing the north pole of the magnet, the anomalies are south poles on the surface and vice versa
It looks like a plasma effect. Perhaps a residue resulting from the magnets initial charging. It also looks like a crop circle, or a trail of impact craters on the moon. I'm thinking the electric charge applied burned the material away causing the charged material to form micromagnets on the surface.
Either someone used tiny coils to burn microdot magnets onto that metal surface, something others have been doing for a few years now, or arcing occured during the high current magnetizing phase and copper/bronze contact points material was plasma welded onto the surface, causing a blocking of the magnetic flux lines.
The very fine, free moving iron talc is super responsive to the magnetic field. It wont stay on non-magnetic imperfections.
interesting - I will add it to the things to consider. Thanks
Thanks to you.
Is alcohol diamagnetic? (Ethanol or methanol? Polar/non-polar.)
I know this comment is very late, but I just discovered this great channel.
I know this is a strange observation but here goes....
Looking at the curved pattern on the magnet reminded of the path a energized particle takes in a magnetic field depending on the type and velocity of the particle.
Something obviously dropped on the magnet and stuck to it. It must be blocking or interfering with the magnetic field, and the iron is simply finding it's way around the drippings blocking the magnet's magnetism.
The clues are ENTIRELY in the manufacturing process. Get a go pro and follow the magnet all the way through the process. It's got to be impurities in the nickel coating. The question is, what could make that larger to smaller spiral pattern. What could make that line? Could it be Leidenfrost effect? Some moisture gets on top of the nickel and bounces across, causing cooling / heating just under the bounce?
Id get a spectral analysis test done on the spots to signify they are a part of the surrounding matrix or something all together different. As an assumption there may have been an impurity or clumping of material in the magnet manufacturing process that is concentrating the flux in these areas. You also may have found something significant here too in magnetohydrodynamics .. I admire how you approach this in such a mindful manner..
these spots are domains where the magnetic moment , spin, is 0 or cancelled out. the permeability in these spots is very low. since the magnetic flux lines prefer high permeability material, they bend around these spots.
the reason for these spots might be oxidation, the nickel plating is not protecting the magnet. rust. many materials lose spin by oxidation. since the electron becomes paired.
I bet if you hook up the magnet to a car battery and drag a single wire across the face you will have the same thing.
The spots on the magnet appear to be diamagnetic, plus the arc they appear to follow looks like it might follow a fibonacci sequence. Did the magnet come from the manufacturer this way, if it did, maybe there is a problem with their magnetization process. Maybe during the soft phase of production, maybe some impurities were introduced and the combination of impurities and the base metal of the magnet are reacting to one another and creating a diamagnetic field inside those areas. Now, the fibonacci sequence that seems to appear, maybe that happened because a particular frequency was introduced when the magnet was soft and before it was magnetized. I've noticed some weird things in videos of cymatic demonstrations of sand or salt reacting with the different frequencies applied to the metal surface. It almost looked like a fibonacci sequence in the sand or salt as the frequency was increased over time. It could have just been the way I was watching the display or it could have been my overactive imagination. Maybe the crystalline structure of the magnet was affected by something as the structure formed. Like the fibonacci sequence that appears everywhere in nature, from the seed placement in a sunflower head to the formation of kernels of corn on the ear. You see the same thing in whirlpools, until the funnel pulls down far enough and then it looks like DNA. Victor Schauberger showed that in his work with whirlpools in rivers. He was then able to use the force formed by the whirlpool to levitate his devices.
I don't know, just a couple of thoughts. Maybe something in my ramblings might help someone come up with a better idea.

Good luck everyone.
Both lines show a decreasing movement. One is curved while the other is straight. It also looks like in these spots the material has been "diluted". Was some type of chemical dropped on the magnet before the final electroplating process? A chemical even when wiped clean, left a residue that couldn't be seen? The surface is too even for an arc or something to have hit it in my opinion. Not sure, just some thoughts. Maybe they will help you, maybe they won't.
That is what happens when a magnet has been coated. Those are lines of magnetism effecting the superficial substance used to coat the Magnet. Maybe minute impuraties.
If yoy want to get far fetched you could suggest the field has generated heat release during periods of maximum distress or magnification of the field strength.
I would hazard a guess that the ‘bubbles’ in the solution are caused by those ‘spots’ on the magnets surface having the characteristics of the opposing pole relative to the surrounding field orientation. This causes the iron fillings in this region to exhibit an opposing charge. So although the iron is attracted to either ‘pole’ the proximity to the surrounding filings induced charge repels the filings from the other filings while still being attracted to the magnets surface. The solutions properties are of interest to me, specifically if they exhibit diamagnetic properties. The induced charge polarity is retained to a degree in the filings so when the locality of the spot changed relative to the iron filings, the induced charge of the filings (again, the properties of that liquid solution are a curiosity to me here) is retained and effects a repelling force to the filings resulting in their persistence to remain in their current configuration.
And the cause of the spots that would effect this characteristic? Best guess is high Voltage arcing (if any signs of electrical machining and/or scarring are present) or a high intensity laser. But specific attributes would have to be met, Ie; the laser beam operating in a pulsed manner and the magnet inadvertently passing in front of the beam. Rolled perhaps? I didn’t pay close enough attention to the nature of the arcs radius, but I did see the dots becoming closer before forming a solid enough looking line.
That my guess after briefly watching video. Probably way off. Lol.
Its not something cheeky like a conductive substance applied to the surface is it?
as one has pointed that using a ferrocell is excellent and trying a magnetic viewer film is pretty good to to see if there are any anomalies in the field,,
the stronger the magnet the smaller the space, centripetal convergence "inertia and acceleration" is "stronger" than the centrifugal divergence "force & motion"... those spots must have a different capacitance when melding the materials used while heating...
I think those marks are either caused by in impact... a on object bouncing against the magnet surface. This would be consistent with the spacing and could damage the domains. If not that... possibly an arc... in this case heat would cause the damage... looking forward to hearing the result :)
Not an impact. That was my first thought and I dropped a 1 inch diameter steel ball on it a few times trying to duplicate the situation and it did not do it. I am exploring some other ideas too. Thanks
What will the *Golden spiral* be doing here?
Possibly an accidental halbach array. Something either didn't get mixed properly or something else got in and poisoned those areas.
Have you found a similar phenomena on other magnets, do they have similar spots on the magnet surface? Could it be caused by imperfections in the magnet? Maybe there is some type of a non-homogeneous area from the opposite pole that leached up to the the top pole before the manufacturing hardening process was completed.
Nope
Well, the magnetic field is stronger around those spots than inside them, this is for sure.
Do those spots just come from poor manufacturing process of the magnet??
This is a correct statement. The higher strength field is on the outer circumference of the field. I will give the exact readings next week. Now that you have gotten that - what on earth could drop magnetic field strength that much in 0.1 mm?
@@SuperMagnetMan hmmm. What if one was to zap a narrow high voltage bolt through the magnet? That would easily have enough energy to demagnetize the channel it went through.
In the manufacturing process it's imperative to keep the material from oxidation my thought is something went awry before or during the process of coating.
SuperMagnetMan
But the persistence of the ‘displaced’ medium even when the locality of the effected magnet is no longer beneath it?
If you look at your magnet, you see the circles . they space at what looks like a phi ratio. My theory is this. The magnetic density is higher in those particular circle "spot" formations. The manufacturing of a magnet could cause this. Naturally magnets create a torodal field. Those spots are naturally created due to the core base of magnetism. Higher density magnetism ... In a torodal field formation.
Ah a Conditional Problem you've set up the Condition and want others to figure out the Solution.
When imperfections are found it's easy to figure out it's in the Manufacturing Process. But what would cause this, so let's narrow it down a little further. Great care is taken to prevent Oxidation from taking place so One possibility could have been a defect in the Plastic Wrap possibly Air Bubbles that Burst when sealing.
Another possibility could be in the coating (plating) process or even in the original blending of the metal. I think Oxidation would be my first Choice since it formed on the Surface...
It looks like there's a Fibonacci number. I assume if the magnet was bigger it would increase the amount of dots across the face. Does this only happen in round magnets that are flat on the top and the bottom. And can you affect the dots with another magnet on the side or the
It might have been due to a momentary discharge of electricity perhaps from another piece of machinery being turned on, or off elsewhere in the building, which could hypothetically leave a symmetrically graduated trail of observable inverse energy, given during a relatively soft stage of the forming process. So the mark would then appear to indicate a proportional change, or difference in the subsequent net unit of charge given to an otherwise normal direction of charge expected in standard models of typical magnetism. Kind of like a fly-back, or a randomly skipping spark of electricity, but simultaneously slowed by the binding forces of the magnetic domains.
This reminds me a lot of Fractal Geometry !
I think it’s a C.M.E. a Coronal Magnetic Ejection.
Maybe one of the solvents or acid used in the manufacturing of the magnet maleic, glycolic, and L-ascorbic acids was spilled on it. This may leach out the impurities in the magnet & causing an effect liike cold wield together under pressure, except in this case it interacted with the acid and pressure and locking the defect in place . Try using one of your testers an see if there is a difference that can be detected. I did notice the material was smoother in those regions compared to grainy part.
Interesting effect. Could it be captured "Dielectric Field Bubbles" (Reminds me of Sun Spots). ... Regards DC
The dark spots appear to be oxidized or melted, perhaps caused by the application of a pulsed high current applied via the surface. This could have been done intentionally, through obstructions on the face during the magnetization process, or by heating the spots past the currie temperature of the material. What are your thoughts on it?
I know exactly what this is, but I do not know how you mange to make this. If you can mange to recreate, what happen when manufacturing the magnet, we will see the frist one of a kind method to design complex magnetic field lines. Please go and find out what happen at the manufacturing place, for science. if it happen once I'm sure some other magnets from the same place end up with the same "defaults".
It looks like the manufacturer has unknowingly created magnetic pixels,polymagnets, have you tested the spots with a polarity device
Impurities in the sintering process creating a diamagnetic area?
You 3D printed a sort of Halbach array on the surface of the magnet!
Thanks for your interesting videos. Just a guess here, each spot might be a precession zone where field is precessing between Earths magnetic field and the magnet's own magnetic field. So each spot like a spinning child's top which is wobbling at some very high rate. Inducing current in your Iron particles which leads to an equal but opposite magnetisation to the applied field due to Lenz effect. If true, under right conditions it might be able to be harvested as free energy?
by the pattern, it looks like a Fibonacci distance was decreasing in distance. I believe it was something bouncing on it as it decayed in height. The circular arc has me puzzled if it was the same radius or more of a spiral decay also.
Thanks Dan - I am baffled too. I agree that it looks like something bounced across it. I have not had anything really around it but I am thinking of a few of these ideas and and seeing how I can recreate them. I would like to come up with something that is repeatable.
@@SuperMagnetMan could you check and see if the pattern was in a spiral or a circle? I saw one comment that mention welding and I think it could be molten slag that may have bounced on the surface. It's just a guess. The angle is confusing. You do nice videos also. I made one of the accelerated magnet spiraling force but it was just interesting for something to ponder about.
A lot if guesswork describing the obvious possibilities that may have caused this pattern on the magnet, but what he is asking (I think, kid keeps distracting me) is what are we seeing in that solution, and what exactly is the attributes of the defects that could cause this?
Looks like it was hit with pulses from a high power laser that made small spots where the Currie point was reached..idk maybe
Go buy a ferrocell. It'll help show the fine parts of the field lines.
This phenomena is part of what is called "incommensurability" by Charles Protues Steinmetz, the wizard who helped General Electric become big.
Iron is actually equal parts dielectric material and conductor.
It's precisely in the middle of the Karhlrule nucleotide chart, along with his brothers nickel and Cobalt. These are the only ferromagnetic materials all other materials are diamagnetic (or paramagnetic.)
This is because the quote Quantum spin States are in equal parts conductor and capacitor.
I am only highlighting certain factoids in a comment section of RUclips, but far better detail can be given in the book.
could it be because the magnetism isn't straight from the bottom to the top isn't perfectly in line if it was slightly out it might cause something like that to happen or maybe if you tried to put more of an angle to the magnetism at an angle through it it would make it even more pronounced
The spots look like the same colour as the uncoated magnet without the nickel coating, wonder if the nickel interferes with it.
You received the magnet 5years ago - it was normal. The Fibonacci Sequence dots appeared later...
***********💡 idea1
My guess is that over the years, the magnetic field shifted - left. But why? ( please disect that extra large magnetic in slices to examine those dots position.)
***********💡 idea 2
I wonder what current ( micro current) was needed to do this. Going into some sci-fi speculation here by saying, ( 1Hendry = 1Wb / 1Amp) that micro current from the buildings own lights, wiring or circuits may have altered that magnet. As it is a pretty large magnet about 15cm long.
**************💡 idea 3
Is there an extra property for very large magnets, that get crushed under its own magnetic field? Maybe the iron material is to weak for the neodymium type magnetic force field? After a period off 1500days, the iron "rusted" in a "self-inductance" freakish way. Why I say self-inductance, is because off the spiral shape.
************💡 idea 4
Wonder if it's a manufacturing offset. Perhaps, the one side is a micrometer (1micrometer) less then the other side. Is there a movie 🎥 off how that magnet was made. Normal Magnets do lose their properties at a normal rate.
When was manufacturing date …??????????
My first thought was of the similarity to some of the crop circle patterns but if I take off my tin foil hat I'd have to go with a manufacturing defect. How are those large magnets made?
Those are from where the plasmatic “wave” pulse was applied to the metal to create the field. That’s a Fibonacci spiral of creation.
acid drops hit the surface and caused the domains to randomize because of partial dissolving
Is it possible something very hot dropped onto the surface of the magnet, which would have removes the magnetism from the spotted area. Because heat is the only thing to remove magnetism. Here is an idea, what would haven if you drip some liquid nitrogen on the spots for minute or two.....the magnetic force would return.....
Ken Wheeler, I'm looking at you.
tatooed monkey. Watch Scientific Lee when Ken learned it from.
Could cylinders have a helix property that innately trend this pattern?
any idea how deep the anomalies register into the surface?. have you tried other forms of fero-fluid? need to see third dimensional plot.
but it looks to me like some form of impact due to the curve and disipating trail. like something magnetic traveling through 3D pulled to surface at an angle then came to rest in a short set of bounces
maybe flaws in the metal as in www.wermac.org/others/ndt_mpi.html
The question is if you buy another of these magnets does it also have these spots?
I also have to wonder wonder what the manufacturing process was. Does the magnet get magnetized while its still cooling? If so this might cause the dendrites of the metal to form differently as the magnets own magnetic field grows stronger during the cooling/magnetization process. I notice the spots are at an increasing width apart.
Curve linear vectors, cetrepedal force vector in aether.
Looks like SUN spots, they are magnetic !
Curious of the spots in 3-D , are the spots straight lines or
Do they bend ?
Well, first you need to know what liquid marks are there on the surface of magnet.
Then we can hypothesise.
You could have at least told us the gauss meter readings on and around those spots, though you have since commented that the field strength is much lower within the spots, but is it reversed in polarity? You also already commented that the magnet didn't come like this when new, so that rules out arcing during production, and that bouncing a steel ball on it didn't replicate the spots. All I can tell from experience is that I had a small rectangular magnet break in two pieces, and on one piece the polarities switched. If that would happen within a large surface somehow, the stronger surrounding field would effectively demagnetize the spot with the reversed polarity, causing a low gauss reading. So my guess based on what you told us so far is, the spots got heated above 80 C or something reversed the polarity in those spots and then it was demagnetized. That doesn't explain the pattern though.
Now please respond to my e-mail where I referenced a video of spinning magnets.
Hey, thanks for the input - I do have the gauss readings and it will be in the video update tomorrow:) But, since you asked the center of the spots ranges from 3200 to 4200 gauss and the area immediately around it is 5,600 gauss. That presents the next question - how in the world can it drop 2,000 gauss in a millimeter???
@@SuperMagnetMan At 2:15 you can see a deeper indentation having the same effect. Obviously the nickel coating is 'compromised' in both the spots and at this dent, this loss of ferromagnetic material in itself will reduce the gauss reading, but not by that much. However, maybe oxidation started at the places where the coating was damaged, working downward into the magnet, and I'm guessing this can explain the further reduction in flux. Maybe someone spilled something slightly acidic/corrosive (while the magnet was moving, causing the patterns) and time did the rest.
The spots come from a energized wire skipping across the surface of magnet,during the charge of the battery,?,maybe
That was the first thing that crossed my mind.
Possibly even something like a rapidly pulsating taser wire dragged over it.
Chemical droplets that have an oxidizing effect on the metallic components under the surface plating.
Prior to the plating process during manufacture.
What about drops of hot coffee that demagnitized a part ? :) I know it sounds silly, but you never know what your colleague Harry Nothandy did while you were not looking ;)
Was dirt on the charge pad there hot spots from magnetism when unit was charged.
Probably oxidation or rust occured, holes in the plastic wrap would be my guess...
For real the answer to this is simple.
I'm late, but I'm guessing impurities in the magnet?
Golden ratio.Fabonacci.
Can we see this in every magnet ?
I saw a rod that when facing up ward is always North the poles jump. When you turn it. Can this be made? Do you know about this?? look up geet rod
It is showing part of the magnetic field lines
Slight error in magnet creation?
I would think it is impurities in the magnet.
Maybe it is a impurety in the manufakture prozess of the Magnet, where the Neodymium-Iron-Bor is not perfekt mixed and respondes diffrent in the prozess of dielectic Magnetisation.
NO, I guess I should have also shown the other end of the magnet because this does not happen on the other end and it does not happen on the clear side of the magnet. It only happened over the spots.
The crop circle marks may just be oxide spots caused by exposure to drops of an acidic substance that reacted with the surface & perhaps even the subsurface to some degree. Its presence is both visible & measurable. Or perhaps drips of something very hot/molten is also a possibility.
What can stop magnetic fields? Iirc nothing can you remove the anomaly from the magnet for test?
Actually nothing can stop magnetic fields - iron can bend the magnetic fields and mumetal can reduce it some while you are using it below a few hundred gauss.
defective inconsistent mix
All I can think is just poor manufacturing process while building the magnet...
Looks like casting impurities
No, this is just in the nickel plating on the surface. The magnet is actually triple plated - Nickel - Copper - Nickel and these spots are on the top layer of nickel. They were not there when I got the magnet.
@@SuperMagnetMan the triple plating, including sandwiched dielectric copper, can be an interresting hint.
don't copyright the solution if it makes money everyone should know it
did someone grab an arc welder are arc across the magnet
It is a way to manufacture stronger field magnets. Explained on this video: ruclips.net/video/IANBoybVApQ/видео.html
