Behavior of a Magnet Falling Through a Copper Tube 1. Falling in Air: When a magnet falls through the air, it accelerates continuously due to gravity. The speed keeps increasing over time because there is minimal resistance opposing the motion. 2. Falling Through a Copper Tube: Induction of Eddy Currents: As the magnet enters the copper tube, it creates a changing magnetic field that induces eddy currents in the tube’s walls. These currents generate their own magnetic field, which opposes the motion of the magnet (according to Lenz’s Law). Opposing Force: The opposing force from the eddy currents increases with the speed of the magnet. This means the faster the magnet moves, the stronger the opposing force becomes. Speed Changes Inside the Tube: Acceleration Phase: Initially, the magnet accelerates as it falls due to gravity. Deceleration Phase: As the magnet speeds up, the opposing force from eddy currents grows stronger, reducing the rate of acceleration. The magnet doesn’t continue to speed up indefinitely because the opposing force balances out the gravitational pull. Constant Speed (Terminal Velocity): Eventually, the opposing force becomes equal to the gravitational force, and the magnet reaches a constant speed called terminal velocity. This is the maximum speed it will attain while inside the tube. 3. Relative Speed Perception: In the Tube vs. Free Air: In free air, the magnet would continue to accelerate, reaching a higher speed over time. However, inside the tube, the speed becomes constant, which may seem like a decrease compared to the continuous acceleration in free fall. Conclusion: The magnet’s speed inside the copper tube becomes constant due to the opposing force of eddy currents, while in free air, it would keep increasing. This is why the speed inside the tube appears to "decrease" compared to free fall, though it actually just stabilizes.

What kind of magnets are those?

Thank you sooo much for this Clarification 💖

I remember doing this to my Box TV and it was permanatly damaged. I had to deal with this for a few month untill I got a new TV. This was 2013 and I was 7.

Are there any safty conserns with magnets coming off and being swallowed By young children

I did this and my Tv turned into a ps9😂🤣

Can this be done wit plumbing copper pipe?

Oh my god!

Yet the earth perfectly stays going around the sun. I guess gravity is easier to stabalize shit with than magnetism

So trump had magnets on his podium

이거 보고 신기해서 똑같이 하니까 엄마가 한대 때림 ㅋ

@KJMagnetics PLEASE PIN (for good reason) Folks, please remember to keep magnets away from electronic devices like phones and laptops. They could brick the device!

Watching this is infinitely more entertaining than the time my cousin risked damaging my tv the same way.

when I was little, I used a small emant on a television a little bigger and bigger than in this video, the result was a purple and yellow trace appeared on both sides of the screen, I tried to remove them remove but I get worse all! so I acted as if nothing had happened when they asked me the question.

I kinda did the same when i was little, though my magnets weren't strong enough.

I want to find a CRT/VHS combo to record effects on, but these used TVs prices are getting insane

Such color

If you put metal plates at the poles of the ceramic magnet to close the magnetic circuit it will be able to support a lot more weight. I managed to lift 60 lbs with one of those 2X1X1/2 inch ceramic magnets.

The idea of a hand cranked backpacking/camping stove is very intriguing

Why be wary of stainless steel that’s not magnetic at all?

Dumb. Boring. Waste of time...

The eddy current induced by a changing magnetic field produces a magnetic field that opposes the flux of the initial magnetic field i think

I did this at a play place a grocery store had. there were magnet toys on the floor in front of a tv playing The Croods, and I was bored playing with them, so I was looking for places to stick them to. I tried the edge of the tv screen, and I saw cool rainbow effects on the screen, and then I put it right to the screen. After a couple minute, an employee noticed, and pulled me away and told me to play with something else. I don't know if they told my mom when she picked me up

Only geezers are allowed to watch this 😎

If the parts of the lock get magnetised… is this a good idea?

Problems with MHDs: Water (fresh or salt) has a weak magnetic dipole, and isn't easily influenced by magnets, on a small scale it looks efficient, moving something big escalates the efficiency problem. The MHD generate highly turbulent (and subsequently noisy) exhaust flows as a result Silent is not a word anyone would use and the moment you waste money to put those on a sub, pretty much everyone in the world will know exactly where you are.

Is the one stuck on to the lid a magnet or a piece of metal?

What I'm wondering is could a magnet stop a solid copped bullet. When a magnet is thrown at a copper plate it creates and em field that slows the magnet and the strength of the field increases the harder it's thrown. It makes the copper plate hot from absorbing the inertial energy. I doubt the magnet would stop a bullet shot right at it but maybe if it's shot down a rail lined with magnets it might. I thought of the idea when I saw a video about using a swing arm to launch a small projectile into space.

Next step- using air pressured motor.

მაგარია,ნიჭიერი ხარ.

A bin works too :p but hey, "everything looks like a nail" - right? jkjk

No tried doom

The flux diagram of a Halbach array special arrangement of permanent magnets that augments the magnetic field on one side of the array while cancelling the field to near zero on the other side.[1][2] This is achieved by having a spatially rotating pattern of magnetisation.

No sparks? No pyrophoric shenanigans??

reminds me of fucking around in gmod with that tv prop that shows the player's pov on the screen

Is thread good enough for line?

what would happen if you roll one of those magnetic balls along a sheet of aluminum? does it not work because the magnet might switch poles as it rolls?

What transistor did you use?

Can I use red copper wire for this? Please I need an answer

Nice video. One bit of irony: regardless the corrosion/rust, those magnets are still attractive. Irony is an interesting construct in our English language, but often is not recognized. One easy way to know if it's irony: put a magnet against it. If it sticks, it's irony.

Wow an afternoon well spent

I just figgured out how to harness that power of resistance. I will be dead soon.

thank you!

Why did you fill in the center, it makes it harder to see the point of impact.

Con Sonar. CRAZY IVAN!!!
