Mapping monster magnets magnetic field

How large is the magnetic field from my two largest magnets? Are the magnetic fields from a 200x50 and 150x100 mm magnet similar? Is my house even big enough for this experiment? Let's find out!

Now I know why all my compasses seem to point towards your house.

Thank you for making magnetic science awesome! My brain has been massaged. 👍

Good god, I almost had a heart attack looking at that thumbnail. Glad it was edited.

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.

I learn so much from your videos, you are a great teacher.

0:38 I was like oh shit how are they so close to each other and then I realized it was just a mix of two vids.




edit: omgf thanks for 100 likes ive never gotten that many

It is a great day when brainiac75 posts

It's as if a huge force reached out To my notification Box!

It was awesome to see the wires coiling around the edges of the magnet. Really enjoyed the video. Thanks Mr. Brian!

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.

Does anybody else realize that the Tesla meter uses Android?

[dougthfret]

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.

[JasonKerlin]

Outstanding, I love electromagnetism, great video on magnet field strength. Thanks to you, sir.

[amgdboi]

That magnet has a massive field (great video! Keep it up!)

[nopparuj]

Wow that magnet meter is running Android.

[horatiudanciu]

i was so bored until i saw this . i love magnets and things 'bout them. thx brainiac :D

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.

The wire coiling on the magnet at the end is really cool! Love these magnet videos. Subscribed :)

8:45 literally the most satisfying thing ive ever seen

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?
