Have you considered mounting an RGB led on the probe and connect that to your meter so it would change colour according to the measurements? Then you can take a long exposure in the dark while waving the probe around to create a visual map of the field (light painting). Of course you need to be careful so that the current flowing through the wires and led doesn't affect your measurements.
Now, that's thinking out of the box :) Great idea, but I will not be doing it with this precision instrument. The probe alone is worth around $1600... Thanks for watching!
It makes sense to me if I think of it like hooking up batteries either in series or parallel. One way will increase your voltage while the other increases capacity. Seems to me pretty similar to your monster magnet tests. Your double magnet configuration seems to have more pull on the poles because it's 2 magnets instead of 1 and your 1 magnet configuration had more draw on the midline on the side because it was just a single massive magnet. It didn't have the seam that the 2 magnets had and was stronger for it.
Seems unreliable. Usually part of why this high end equipment is so expensive is because of the incredible robust build both physically and firmware wise as well as the extensive testing that goes into it. Slapping something like android which is a mess of a system based on a million patches that nobody really knows when it works and when it doesn't. I dunnoooooooooo
@@bjordsvennson2726 Well I do work in mobile app development with both android and ios. And know a bit about the history of android and how it came to be. Not to mention I've had nothing but android phones for the last 9 years. Is anyone looking for "cheaper" as a selling point in their high end equipment? Lastly, I think It would be beneficial if you're trying to make a high performance racing car in the present day, you should design the wheels from the ground up, not start with a set of 1925 Buick wheels and patch them as you go.
You're not joking about those magnets not being toys. I get nervous just watching you handle them! I know you are very careful, but, PLEASE BE CAREFUL! Love your channel, BTW.
Have you ever considered hooking the probe up to a 3 axis CNC machine and recording the data from all three axes of the probe and the CNC position data? That way you could map the actual vector field in 3-Space around the magnet. If you want, I could probably write some mathematica code to render the field from the data if you ever get around to it.
Have you ever just thrown a large cloud of iron powder into all the air surrounding a large magnet? Film it with a high speed camera. Is it possible to get oppositely charged very fine particulates/powder to try? I'm interested in if it's possible to get a visual 3d view of the field? Or has this been done?
Yes, all the things I have to take into consideration with my large therapy magnets. I like to keep them in place with a steal washer but the washer will always go to the edge and if possible on the edge between the negative and positive. Which brings us back to the magnetic field preference for the material it travels through. When I tested the field strength in front of my body with the magnet on my back it is stronger thatn at the same distance through the air.
attracting forces in a magnetic field are caused by gradients in the magnetic flux, not the flux itself. A very strong but perfectly homogeneous magnetic field would only turn around ferromagnetic objects, not attract them. This is why compass needles don't experience a net force towards any pole. This is also why the attracting forces are largest close to the edges of magnets, where the field changes most strongly with distance, i.e., the field gradient is large compared to the center.
Because water is a diamagnetic fluid does that mean it would be possible to create a vortex in a glass of water without the actual magnet being in contact with the water itself?
Thanks. The first 4 years in my RUclips career I made 0 cents :) The partner program wasn't available in Denmark until February 2013, so yes - this is primarily for the passion of video making and knowledge sharing :)
I was thinking the same thing. One caveat is that the motors and metals on the robot arm will throw off the readings a little, so you'll still need a few manual measurements for confirmation.
I think it would be really cool to somehow get the magnet close to a cnc machine and make a 3d map of the magnetic field. It would make for some really cool visuals. Where are you going to find a cnc machine that can accomodate this thing without flipping out though? lol
So if you were to go out to an empty field what would your tesla meter read. How much of that change was due the the interference of other sources closer and by altering their field you altered your readings? I know electricity puts out magnetic fields but not sure if your meter would pick those up and still not positive on the effect of a slow moving magnetic field effects on the emf field from electricity.
Quick tip you shouldn't yse grid lines for graphs as they make it difficult to see the trend. Optical illusions can make them look wavey even though they are not.
Why did you bother checking the 150G safety distance when you still just poke it with the probe anyway and go to 4.5kG? Or was the safety distance for changing magnetic fields so that you didn't want to rotate the magnet when the probe was closer than that?
You have to remember, that like all dipole fields, magnetic field strength decreases with the inverse CUBE of the distance. So even if they are very strong from very close, you don't have to go very far away for the field to drop off prohibitively and then to undetectably low levels. It's because there's a south pole and a north pole together, as there are no magnetic monopoles. You would see the same thing if you had a large positive charge right next to a large negative charge, rather than a single charge of one sign, it falls off with the inverse cube and not the inverse square because the 2 opposite sign sources cancel each other out more completely the futher away you get from them. It's also the same with tidal forces in gravity, the dipole there is the 2 sides of the object experiencing the tidal forces, which relative to each other are a plus and a minus.
Question4all: Are magnetic fields homogenous or are they made of alternating lines (like strong-weak-strong-weak...) resembling blades of grass or teeth of a haircomb? I know how iron dust becomes spiky near a magnet, but how can we know whether that proves anything? Is it the magnetic flux that is concentrated along thin lines or is it just how iron dust behaves even though the magnetic flux is evenly distributed?
It is the teslameter's electronics box that needs to be at max 150 G. I wanted to see how close I can have the box while measuring on these giant magnets. The teslameter's probe will be fine in magnetic fields as high as 35 T / 350000 G. Thanks for watching!
What is it that turns out, if you throw an iron loop on a magnet, then the field will spread further? Cool! Although I thought for such magnets the field strength is about one and a half Tesla, and here there is quite a bit.
I'd imagine magnetic fields behave similar to gravity as far how the effect spans infinitely, just getting exponentially weaker the further you go. That sure is one sensitive probe though.
Wow that was awesome thank you so much for making this it is going to be a very interesting conversation with my friends about this video thank you for all the hard work that you are doing keep up the great work you have no idea how much your videos are useful and the way you deliver the information is amazing I hope I'll be able to meet you one day you truly inspire me to keep learning new things thank you And as always : greetings from Iran ❤️🌷
Hello, Have you ever broke any of your magnets? I am interested because I have and from what I see on RUclips many others have also. I hope you post many more videos! This one was great!
It would be great to compare this with different electromagnets. And measure the field strength in the air gaps especially with an electromagnet with an almost closed core! :)
Have you tried a magnetometer app on your phone? I installed a few to try on mine before going for an MRI and could definitely see the change in x-y-z strengths depending on the direction and how close I was to the MRI room (I did not bring my phone inside of course ;-)
No wonder the warning at the beginning is there, I recently salvaged some extremely thin magnets from a hard drive and the magnets pinched me enough to make by finger start bleeding from the pressure. Imagine what these ones would do.
What i wonder is how is the shipping and storage of such magnets done. Like, you can't simply put them in the mail and send it right? But i don't know, would you need a truck that isn't made of metal? i don't think such thing even exists.... And about storing them in your house, how much meters apart you keep them from each other? and don't they mess with other electronics? And do you put them in some protective box? Magnets are amazing, like your videos :)
Hey Brainiac! I Have a idea how to connect two magnets. Do you have tried to pass two magnets through, a aluminium/copper pipe from two different ends?
Does it really go on forever? Light (an electromagnetic wave) is quantized into photons. At a long enough distance a light source is on or off. Is this electromagnetic fluctuation somehow quantized by the plank length? My instincts tell me that if light is quantized, all electromagnetic fluctuations would be...

You need to create T-shirt’s. I love go buy tees to support my fav channels.

I wonder if those magnets could be strong enough to pull a nail out of wood. Like the nails in the floor holding the house together under your carpet.
Probably not. If you had nailed down a piece of steel, maybe. But there is just not enough material to pull on. It would be interesting to see him try
Your right!
Cool video as always, but I'll admit most of it went completely over my head XD
it was cool to watch the meter speed up inversely via the sq of the distance as you got closer.
Its actually an inverse cube relation, due to dipole forces cancelling out.
Lol i love how you made the magnet stand with lego 9:30
Why did it take RUclips a week to let me know you uploaded? Ridiculous. Ridiculously good video.
1:30 now i am realize that lake shore is actually an android.

Can you get an copper plate and let it Swing near the Magnets? :)
You should put the magnet under a transparent board and dump some iron dust onto it. It would be interesting to see how big the lines would get.
Is this particular model of magnet actually used for anything besides cool Braniac videos?
Good question. It does seem impractical to have a permanent magnet so powerful anywhere
Bruh, I just marathoned some of your older videos and a new video’s out, awesome!
You can see the magnetic field, bloch wall and poles of magnet in 3D if you use ferrocell.
There is multiple magnetic field around and in the house.
Does that affect the reading on the Tesla meter?
Dude you are awesome!
That metal ball going toward the edge of the large magnet shows its power. There is only a single frame where you can see it moving
So if you were to go out to an empty field what would your tesla meter read. How much of that change was due the the interference of other sources closer and by altering their field you altered your readings?
I know electricity puts out magnetic fields but not sure if your meter would pick those up and still not positive on the effect of a slow moving magnetic field effects on the emf field from electricity.
The angry photographer explains magnetic fields with ferrofluid and a glass plate.
the smaller the space the greater the capacitance, this is why the stronger magnet has a smaller field and also explains the Casimir effect
It would have been better to plot the magnetic field on a log/log graph to show the 1/r3 relationship.
Outstanding alliteration
Very helpful timecodes!

Although a dipole magnetic field decays at an inverse cube rate, whereas gravity decays at an inverse square rate.
