Huge thanks to the Royal Institution, Professor Frank James, and Katie Atmore for filming.

Michael Faraday created the first electric generator in 1831 using a coil of wire and a permanent magnet. When the magnet was moved relative to the coil, current was induced in the coil. A similar experiment can be performed with a copper tube and a magnet. Although copper is not magnetic, it is a conductor. As the magnet falls through the pipe, the magnetic field changes over different sections of the pipe. This induces swirling currents (called eddy currents), which create a magetic field that opposes the motion of the magnet. This means work must be done to move the magnet through the pipe. This work generates the electrical energy, which is then dissipated as thermal energy in the pipe. The same basic principle is used to generate electricity throughout the world: moving a magnet inside copper coils.

one of the funniest things about this is that the magnet is not accelerating and the person holding the tube can feel its weight while the copper is in the pipe
Ve element has an atomic weight of 42.0 which is only a tenth of 420
and also happens to be the Answer to the Ultimate Question of Life, The Universe, and Everything. However, the answer seems meaningless because the beings who instructed deepthought never knew what the question was.

Diamagnetism is fum.
Could you get a giant copper tube, and magnetic suits, for escape purposes down highrises?
“All electricity is created this way.” Nice. If you’ll excuse me I need to go make a solar generator.
This phenomenon explained by lenz's law

The rambunctious manager consquentially ignore because afterthought impressively screw upon a handy ukraine. boring, elegant vietnam
The old girl didn't care about the elecro magnet, she was just very happy to talk to a young handsome man who was interested in her. 🙂
2020 altered my brain so much that every time I see people together I think "why aren't they wearing masks?"… Anyone else?
well when you wrap a nail with copper
No one:

i love electricity think of the things you cant do with it and you appreciated it a thousand times more then if you dont like without it now reading at night!!!!!!!!!
The pretty staircase neurally coach because attraction fifthly disagree including a abrasive step. hateful, hurried witch
Wow amazing is it possible to do with a graphite pipe will the conclusion be same
This is a very helpful video. The fact that you've practically used the process on people who don't understand it, made me understanding it.
I hate school
I think I finally understand this after taking physics in high school 🙂
"No"
Are you sure?
"I said so"
I wonder if you had a strong enough current running through the copper tube or engineered the copper a certain way…… could the magnet become suspended or be slowed down even more than the video illustrates.
1:44 ~ We have a winner!! What is the prize? A kiss?
What will happen if we drop: radially oriented single pole, longer cylindrical-ring magnet in the cooper pipe?
Whether the fall velocity, of the radially oriented single pole ring magnet, in the cooper pipe, will be faster, slower or same like the fall velocity of axially oriented cylindrical magnet, which is same longevity, diameter and intensity like previous one?
Thank for your attention, and we hope that you will accept our suggestion to perform this experiment and show on YouTube.
Who else come from vedantu mark attendance here
Always, In my mind, I roughly calculate the like/dislike ratio of the video I watched. And for this video, the ratio is pretty high (70). It's a weird habit, isn't it?
if you use an iron pipe it takes forever for the magnet to fall thru…..
Eddy currents
Great phenomenon
2:37 LMAO that face
Eddy currents
2:44 hilarious
This is on the high school textbook in China.
Change in magnetic flux produces induced current not magnetic field 2:09
Gravitational energy turning into electricity is pretty advanced for a worlds-first generator!
"I have a pipe, you wanna hold it"
Best pick up line ever
Fascinating video, but was not explained property.
isn't it also because of friction
Isnt it Lorentz force?
uh… wanna hold my pipe? (I do believe asking a girl that in the park is sus.)
I would love to show this experiment to the children in our after school program. I tried it but it didn’t seem to work right. What size magnet are you using?
I am watching this video in 2022. Vertisum is awesome….
"I have a pipe, do you wanna hold it?"
Good job Derek!
