That screen "zoom bulge" effect made me chuckle
Indeed. Please use it in more videos!
As an educator, I’d like to let you know that one of the things I get from your videos is that sense of wonder I had as a kid. That then motivates me to explore a topic further. Thank you.
7:48 "Have my son stand behind me" - Ah, another convenient contraption you've made :)
Wouldn't recommend it. People build those things because it's easy and the tools are free, but if anything breaks, tech support is a nightmare. You might think you'll just fix it yourself with some spare parts from Granddad, but big surgery made that illegal.
Great idea! I giggled when you struggled with the tools near the magnet. I know exactly how challenging that can be... You know its coming and prepare for it, but you just can't compensate for the quickly increasing strength of the magnetic field near the magnet x)
I did some work on some magnetic stuff back in the day, we had some special alloy tools which made it a lot easier. I think they were just stainless steel, but I can't remember, I remember them being expensive however.
@@ColtaineCrows Neodymium magnets are unbelievable compared to any of the past magnetics most of us old guys are familiar with. Every warning about pinch danger for any neodmag larger than two nickels stacked together is for real. Blood blisters for magnets the size of a quarter or a domino. Crush bone on neodmags 52 about the size of Tech Ingredients' rig here. Loose fingers and other chunks of skin on a 6" diameter magnet. The holding force is not an exaggeration. Put the weight of a refrigerator on just that finger and it's going places.
DO NOT LEAVE MAGNETS of any kind where ANY KID can get to them. If they're stupid, and we're all stupid at some age, they'll swallow them. Bad enough for refrig magnets but DO NOT WAIT AROUND IF NEODYMIUM (shiny) magnets. If they swallow a bunch at one time connected, they might pass them in the poo but still straight to hospital. If they pop them in their mouth like popcorn, they're going to end up in surgery immediately. (muscular distortion of intestinal wall > huge shear vectors where pinned by neodymium pair or cluster).
All that said, they are fantastic to try out ideas that weren't effective back in the day (It took me a few nips to forget the old-magnet mindset - scary these are) that may show noticeable efficiency now.
There is more to magnetic resonance than we understand. Just like hitting a certain note in a bathroom, oscillating magnetic fields need a rethink toward new materials and methods.
Supercapacitors able to be quick fed transient and anomalous emfs that are now wasted can add up harvested. Much of our math on efficiency relies on the permeability of the magnetic and reluctance of alter-magnetic materials which are derived in non-combined standard lab replications. Experimentation is happening because magnetic power and energy storage options are available. The gold standard is electric flying. Power/Weight ratio can be offset by unconventional efficiency schemes using short burst hot and long term simmer power management. Great time to be alive and curious in these things. Great FREE resources like this guy here.
The Bedini wheel as explained and demonstrated by Great Scott showed some interesting strangeness in the results but only because he can diagram and explain his fabrication and then measure and reason on the results. Might be worth replicating his effort. Hate to encourage the lunatic fringe and I've seen the "free energy" videos til I'm sick but it was a surprising outcome and those are always happy accidents.
Needs some anodized aluminium AN Spanners, maybe that would work
Depending on what you are doing, you can add a bounce layer to one side, so you do not get metal on magnet contact.
@@kguidry7520 Speaking of interesting results, this one one of the neatest things I have seen in magnetics for a long time. They made a magnetism based diode. arxiv.org/pdf/1802.00832.pdf
Here is a different approach involving a 2D honeycomb of permalloy with some directional asymmetry of the hole positions. onlinelibrary.wiley.com/doi/full/10.1002/aelm.201700500
You should use flat steel similar to pallet strap. I've seen it used in some power transformers.
This will eliminate most of the air gaps created by the round wire. It should give you a higher density.
We considered that and it is a good option.
Winding first few turns of that stuff could be an "interesting experience"...
@@blg53 Throw on a liberal amount of Kapton tape, and it should be fine.
@@TechIngredients Could you use shorter strips of metal and layer them similar to bricks first then wrap the wire over the top so as to bring the field lines closer to the gap? Or have I got the wrong end of the stick?
@@TechIngredients would you elaborate on why you choose the wire over the straps. Your response implies you have weighed the options
The fact that your son films for you makes me think he may have an idea how lucky he is to have a Dad like you. I sincerely hope he enjoys every minute of it. Lucky kid!
My thought exactly! Thanks.
The father of the main presenters son would be a heck of a teacher in school. So clear spoken and easy to understand.
How about ferromagnetic fluid? You could make a plastic or aluminium sealable casing and pour the fluid in the casing
No need for fluid, compacted iron powder and an acrylic box might work
I was thinking the same with filings in a binder, would be messier though.
I'm not 2 minutes into this video and I already have to pause to give you props for your quality camera work and editing. Always impressive but that selective screen zoom on the probe was a real nice touch!
This was simply a joy to watch. When you were saying that having to work with big magnets could be “sketchy” I thought, that’s a phrase I’ve never heard here before. It must be true. It was great to just see the laughs with the tools and general mirth in the video. Great as always.
I used to work at a transformer company and they used sheets of high-silicon steel which were layered together to make a laminated core. Apparently it allows a higher magnetic flux density than solid steel. However I can see that working with sheet steel edge-on to a powerful permanent magnet is a recipe for truncated fingers, so your wound coil idea is interesting.
Thanks!
I appreciate the fact that you are willing to take the time from doing other things that you could be doing to provide such Interesting content! Also, that you do so in such an easy to understand manner! Thank you, sincerely!
You are sincerely welcome!
Another quality tech ingredients upload!!!! This channel ROCKS!!!
Once, again: POW! Right out of the park!
Excellent, well done, and interesting.
Thank you.
I'm so glad to have this guy to watch,he is truly amazing
thank you, great vid. clear to the point w/h no swearing or belittleing. thumbs up
Very slick way to build a yoke. I will definitely consider using this in the future. Thanks!
I always learn something on your excellent video's. Thank you as always. Regards Sarah
Amazing that you can make a relatively uniform magnetic field with almost a whole 1 Tesla of field strength. The strongest magnets I ever used were 3 Tesla, and those were liquid-helium cooled superconducting magnets in a Bruker Spectrospin 300 MHz NMR machine about 15 years ago. Go back about 40 or 50 years, and 1 Tesla would probably have been enough to do some basic low-field NMR experiments. If those super-strength rare-earth magnets had existed then, I'm sure they would have been used for that!
Of course the added problem with NMR is that the field strength around the RF probe (which is where the sample-tube goes as well) has to be ABSOLUTELY UNIFORM - no variation at all. NMR instruments typically do this with secondary electromagnet coils called shim-coils, in which the current is adjusted to even out the field strength. In the early days this was done manually while keeping your eye on the field-sensors, but this utter tedium was eventually taken over by a computer, which could do the adjustments much faster.
I wonder if there would be a way of combining the permanent magnet array you show here with a bank of electromagnetic shim coils to make a perfectly uniform field? A standard NMR sample tube is only 5 millimetres wide (with a 40 millimetre sample depth), so the cross sectional area over which the field needs to be uniform is fairly small. If you could do this, you would be on your way to making the core of a home-made NMR instrument. Minus all the RF transmitters, receivers and amplifiers of course, which are a whole other headache.....
Mister, you have great presence. I could find you in a crowd in 2 seconds. This was a really great video, obviously the subject well thought out and something of interest to you, as well. That little laugh at yourself got you a new subscriber. Thanks for what you do.
I love everything about this! I've been making products with N42 mags. Once I discovered "CUP" aka "POT" Magnets, it opened up so many more possibilities.
More wonderful stuff :) Totally enjoy your work, ingenuity and the demos, thank you.
You're welcome!
@@TechIngredients Your Channel Is Overpowered
Man, intelligent people just make better content. Tmbs up.
Thank you!
Did one walk by in the window? I missed that person because all I saw was someone who does not have any clarity of magnetic fields talking too much about nothing.

This is the most underrated channel on youtube.
So cool it’s you and your son giving the world knowledge… thanks guys! Super interesting topics!
I can't believe this channel doesn't have millions of subs! Amazing content guys and girls :)
9:25 I'd be totally down for more inclusion of struggles like this, genuine spontaneous emotion is beautiful!
Great Idea! Helped me a lot. Thank you.
You are informative, concise and to the point. Many other's seem to think that they should also entertain the viewer? Thank you!
That feeling when your father is a mad scientist and has you help him with the experiments.

@@russellzauner sorry, I don't get the reference.
_"Get in the magnetic field Son-ji!"_
Loved this comment....
I didn't even think of how the field would interact with the tools, I was wondering what was happening. Interesting concept, manipulating a magnetic field is significantly more involved than I thought!
Useful to me in many ways. Thank You.
Very ingenious solution! I worked on MRI's a short while and the experience you had with the channel locks was a real problem I had. Most of our tools were beryllium alloy so non-ferrous but drilling access holes for fiber optic cables around a +2T magnetic was an experience I never wish to repeat. Wonderful video keep them coming!
I love this nerd. Makes me feel better about my nerdiness
Glad to be of assistance.
Thanks!
Super clean intro! Congratulations on that. As for the content, I have no comments; it's SUPERB as always.
A man with excellent bench work and theoretical knowledge. Good work sir. One day I will fund you!
I'm always impressed. Am always even more impressed upon realizing that so much more work than we see has gone into your videos. Much gratitude.
Thank you!
This is such a great channel.
Thank you!
I'm auto hitting like before even watching. That's how good the content is
Thanks!
me too
NS Gaming: But that's not very scientific is it?!
Right? I automatically hit "like" before I watch because I know I'm gonna get so engrossed in the video I'll probably forget to later. I've never not liked one of your videos so I know it's a safe bet. Please keep it up. You deserve so many more subs!
I wrap lots of wire and built an aluminum jig/fixture that goes on the lathe and uses the threading settings. Hardest part is like you mentioned chip cleaning before when using magnets. I spend more time in prep cleaning before than I do wrapping.
your approach is wonderful you are a bliss to see !

LOVE
LEARNING!
Would two opposing Halbach array's of magnets also help increase the magnetic field strength inside the gap?
Thanks for including centimeters as well.
I always enjoy your videos. Thanks for being a great teacher.
Excellent video as always! Please don't stress yourself on the whole metric vs imperial measurements just to please some commenters here, the people who it really matters to can easily convert. You make astounding content and we all look forward to you sharing your ideas!
Actually, I don't. It's a bit of an inside joke. The most avid proponents of metric acendency tend to be the same people that look down on Americans because most of us are not multilingual!
Whats really funny is that the Intelligentsia who call us stupid for not using metric as the superior way, never get the joke in the joke when we tell them to come back when they make it too the moon. Not only haven't they made it to the moon unlike us Imperial users, they haven't made it even though using the superior metric systems... :)
Not only are your videos inspiring technology/science wise, they also make me aspire towards having a tidy lab and to develop a more pragmatic approach to my builds and projects. Looking forward to next video whatever it may be!
What a great video. I’ve always wondered what other ways would work to strength the magnetic field. Big blocks of steel are expensive and dangerous and hard to work with. The wrap technique is something I can do and maybe not have every nut and bolt require that it be scraped off my bigger magnets. Thank you! Thank you! Thank you!

As a fabricator, contractor, tradesman, craftsman etc., I know a working man's hands when I see them, so, two gnarly old man's working thumbs up to you sir!
No sissy textbook teacher here boyeez!
Interesting. Makes me think of Edward Leadskalnin works and why he used so much iron with his builds.
Seeing the title I was hoping we would finally get to see some cerrolow 136 being shot into orbit by that monster magnet yoke... but winding magnetic circuits is also an interesting idea :).
This channel deserves more views rather than other youtubers doing sh*t to get famous, for MONETIZATION. I just love educational videos and discovery.. videos like these will teach future generations for years to come.
As always great professional video.
Very cool but i was chomping at the bit to see the rest of the water cooled solid state refrigeration system
when are we seeing the Magnetohydrodynamic motor/generator using that large gap magnet?
Everyone and their brother (not really) has done a mhd motor with conduction. I'd like to see it done with induction.
@@kreynolds1123
How does that work?
@@robbiejames1540 if you change the current in a coil, it creates a changing magnetic field. That changing magnetic fiend induces a current in a conductive metal neat by. The currents in the metal create their own magnetic field in opposition to the initial magnetic field that induced the current. The result is a repulsive force pushing the conductor away.
A Pulsed induction thruster uses a coil to ionizes a gas for a working fluid to use for a thruster to genetate an intense and rapidly changing magnetic field. once the gas is a plasma the changing magnetic field from the coil induces a current in the plasma and that current in the plasma makes its own magnetic field opposing the magnetic field in the coil thus pushing plasma away at a high speed for thrust.
en.m.wikipedia.org/wiki/Pulsed_inductive_thruster
@@kreynolds1123
I see! That's really clever.
@@kreynolds1123
Presumably, that would also work with any sort of conductive material - so you could shoot a plate of metal with it too?
An interesting concept. Having the flux path wrapped around the magnet will help prevent eddy currents.
Wish I had time to just set and watch all your videos, great stuff!!!!!
Man, you are a mine of knowledge !
Would wrapping the copper wire more uniformly with tension help align the magnetic field's better for a higher Tesla Rating???
Copper is not ferromagnetic and neither is aluminum. Although this wrapped magnet looks something like a transformer, the wire serves a completely different function. The wire in a transformer guides the electron flow and it is these electrons that generate the magnetic field. This steel wire guides the magnetic field which is generated by the permanent magnets in the center.
Man I love this video, and the savvy behind it. Good show!
Hello, Thank you Kind Sir for sharing your lifes knowledge with me. You Sir are a God send, Thank you for Helping me understand.
Bailing wire! Almost as useful as duct tape! Fascinating project.
Baling wire has kept a hundred years, and billions of miles, of Ford products running. And I'm betting there's a stash of it on the ISS.
"So I built another assembly to make this a little more convenient." ...I was all hyped up for the lathe. Not going to lie, a little disappointed. Maybe in version 2.0, because if there's one thing I've learned by watching your channel, it's that we never see anything just once and you're always improving. Thanks for doing what you do.
I like the way that you explain the process
Thanks for this video.
This is a modern, much cooler, Mr. Wizard show!
One of the best channels on RUclips. Was wondering your background. Any videos talking about you, or telling what you did before or currently? I guess College professor.
Ryan Fiorini They're notoriously secretive about their identities.
@@brainmind4070 Thanks for that. I just started watching.
The same people who make sure it gets fed to you make sure you have no idea of what the magnetic field actually looks like, if that helps you gather to whom they are affiliated with. This is a common thread with many of the YT technology channels today. They like to high five one another in the comment sections as well. Probably right next to each other having a coffee thinking about how to gloss over any comprehension of simplicity in design and why that is.
@@lifeunderthemic .The Ellumin-Magneto-ati
@@cannaroe1213 LOL I like it. The grants and funding suppliers at work to keep the same page from ever being turned. Simple comprehension of magnetic fields shows that we've been handed a misrepresentation in crafty sleight of hand.
The fast forward is a great way to show things. TOT does that on his machining videos. I'm seeing the makings of a rail gun
Thank you for an excellent presentation of the subject.
You're welcome!
I mean this in the best possible way, this gentleman reminds me of a cross between Mr. Wizard and Mr. Rodgers. You older folks like me will remember both.
How about using steel ribbon instead of wire? I'd imagine it would be more expensive, but it could be easier to wrap and far more uniform.
Good Idea, even though he did say its only the cross section that is significant. But there would probably be some increase. That's basically a packing problem. Like you said it probably wouldn't be worth the cost for the few percent(if that) increase unless you had some laying around. Or perhaps even just cut long strips of sheet metal.
My intuition (which is likely to be completely wrong) makes me think that two opposing C-shapes out of steel ribbon would be even better as guides but it would not be as practical to build, especially not in a continuous additive process.
The ribbon would work, the result would be more compact, the ultimate performance would be the same and the cost would have been higher
Clem Taylor agree! cold rolled steel wrapping around as used in low frequency transformer style would increase permeability which could increase the inner flux( my thought). Improve rejection to the eddy current to? if the experiment required to reduce the hysteresis loop of the wrapping material then could be a good idea. Good comment Clem.
Keep going! Very informative and recreative topics
Channel deserves much more subscribers compared to most others that use gimmicky graphics, and borrowed filler content 👍👍. Wondering, what would happen, if the wound bobbin(made of laminated mica) of steel is taken out and melted to form a solid block(easier said than done).
On another note, seems like an efficient way to laminate(assuming a thin high temp insulating varnish on the steel wire), to make a low frequency(several hundred Hz)power transformer core, without needing ferrites and high frequencies, while still almost eliminating eddy currents without using the typical laminated El steel plates. Just some 💭
This guy is awesome, its like a fun lecture every video....wait.......it is. very easy to follow, great stuff.
Your an inspiration to us all . God bless you Sir. You too have a lovely evening
Brainiac & Tech Ingredients uploading _magnet_ videos within seconds of each other :)
I love when Tech Ingredients upload videos. When it´s about magnets I'm in paradise xD
Magnets rock! :)
Speaking of myself only; I am not sure how useful this is for me but I guarantee you it is mesmerizelingly interesting. I haven't been exposed to a more interesting site than yours and you have a gift for explaining the principle properties of these subjects in such a through and clear way that I "almost understand" them! But, as I'm sure that the majority of the viewers would agree, we aren't in your league. Please continue this facinating site, I haven't found any other sites that come close in interest level and especially not in your scientific method and working knowledge. I'm a big fan!
Thank you!
I'd like to thank you and the people involved in your RUclips videos. I work the Natural Resouces Canada in a combustion lab and we are in the process of designing and building a Magnetohydrodynamics project. This subject is not aligned perfectly with our expertise. We have learned alot from your videos and it has contributed greatly to the final design and hopefully the success of the research.
Thanks! That is really nice to hear.
How do you make a stronger magnet?
Get it to pump some iron and wrap the flux out of it.
Magnets how do they work?
Minutephysics did a pretty good job of trying to explain it in a concise way in this video. ruclips.net/video/hFAOXdXZ5TM/видео.html
Definitely magic. Check this out (there are better videos showing the effect but this one is good nonetheless) ruclips.net/video/r9Kg69cQteg/видео.html

Thanks!
Think I am going to call you the "Walking Technical Wikipedia" from now on :)
My dad would have smacked me upside the head for trying to use channellocks instead of wrenches to tighten the nuts.
My dad might have had the same thought, but avoided it, fearing an endless debate about why do we have channel locks anyway.
Ha! reminds me of the time I needed a pole for my rain gauge. So, idiot me sawed the head off my mum's broom and broke the blade of my dad's hacksaw in the process. The light of truth hit me when the broom head hit the ground: Annoying one parent was dumb, both together and I was dead.
My dad's comment: 'I told you to never use a metal cutting blade on wood.' He attaches the broomhead back to the handle and takes me to buy a new one for my rain gauge.
Very elegant solution!
Thanks!
Great Video I love watching intelligent helpful videos .
Lol, I love how annoyed he gets at reciting the values in SI! Because you know, 3 furlongs and a sparrow's claw is superior to SI units XD
Sparrow's claw? Is that a Vesper Sparrow, Savannah Sparrow or a Grasshopper Sparrow? :) I hear somewhere that Crowsfeet were used as a measure of time in some places.
You were talking about *_magnetic flux density_* (in tesla), not the *_magnetic field strength._*
Please try to use the correct term. I know everyone uses the terms incorrectly, often including myself, but it´s a big difference.
@@invendelirium Yes they are proportional in this case.
It´s just something that can be confusing, making it important to use the correct term.
Awesome video! Discovered your channel a few minutes ago with the air conditioning setup. Thanks for that. The liquid dessicant stage gave me a good idea for a project where I need to control humidity. Awesome channel!

You made my evening scienterrific, thanks.
I really enjoy your videos you have helped me understand magnetic properties more than any other resource I have sought out.
Thanks!
Nice video shot, thanks for sharing with us, well done :)
A really clever idea .. I'll remember this one.
I, as one, feel that having intelligent people presenting the content works much better, but having worthwhile content on the show makes everything interesting to watch also
I had to laugh a bit when the proper tools were not right there ready to use. Another good show, thank you. Michael said that bye for now my friend.
Nice!!! two water-bending magnets placed close together!!!
Thanks!
Your work place is beautiful. Very nice and clean
Thanks!
Definitely one of the top channels on RUclips. 👍
Thanks!
When you don't want the nut to move, use two and tighten them toward each other and that could alleviate pressure on the carriage device in the middle. You could have saved on the bearings at the ends.
Cool video!
Kudo's for using the proper SI unit tesla. At the risk of splitting hairs, strictly speaking, your meter is measuring magnetic flux density, not magnetic field strength (your wording), for which the units would be ampere per meter (A/m). They are related though, for a given set of circumstances and materials. I like your shop BTW :-) Also, your camera work and editing has improved substantially - congrats on that!
Thanks for the clarification.
Also, thanks for the other comment. Many viewers (and at one point that also included us) do not understand how much effort and learning goes into producing a good video that is easy to watch. We are still learning!
What an expedient solution!
