Enother interesting information: specially for you.
Discussion
- What do you think about this? see, and tell us now.
- YEAH, SCIENCE!!!!!
- what happens if theres a copper bottom and you drop the magnet in, does the magnet just float?
- Could this not become a new frictionless powersource?
- Where do you find a big ass copper pipe like that?
- Otázka dne. Co pád magnetu zpomaluje?
- SCIENCE!
- Does this have a real life application?
- how much force was needed to spin that magnet? Also say if you had a thicker copper tube with a more fit center and a magnetic rod not quite the same center diameter as the copper tube, would it spin faster just because there is more copper to conduct with?what if you had say a stationary copper tube with a magnetic needle spinning while on a crystal (less friction while the needle spins) would that conduct energy?
- Nice. Now go invent something useful! >.<
- The background music makes this video even more beautiful..
- Don't you dare confuse that magnet. It doesn't know how it works.
- See Lenz's law in action. As the magnet falls, it induces a current in the copper pipe. http://ow.ly/wTh9i
- Wow - just WOW!
- And then what happens when you wear a Neodymium magnet suit/ bag-pack in a round copper room? Something like anti-gravity?
- "The magnet induces a current in the copper pipe, which in turn produces a magnetic field. The direction of this current is opposed to the change in the magnet’s field, resulting in the magnet being repelled and thus falling more slowly"
- I heard this creates a lot of heat after a while.Could you lay the copper pipe on it's side with the neodymium magnet inside, block any exit and create a self powering heater?If so, would the magnet eventually melt? And if so, what temperature would it reach and what sort of radiation would it emit?
- Science bitch!
- quick question:Does the pipe gets heavier with the magnet in it ????
- Because science.
- What are the practical applications of such an awesome phenomenon?
- leave it alone!!! youre hurting it!!!!
- What is the music in the background?
- Magnetic suit + small copper room with 50 ft ceilingssounds fun
- Freaky
- Fuckin' magnets.. how do they work?
- So then is there a speed where gravity will be canceled out and the magnet will just keep spinning forever? (Ignoring wind resistance)
- SOOOOOOOOOOOOOOOOO Cool!!!!
- that almost sexual name
- 0:38. done. it's done. you broke gravity. good job.
- I was very productive now im watching all sorts of crazyness. Arigato youtube.
- Cool science, Lenz's Law...
- INDUÇÃO MAGNÉTICAAntes de comentar, alguns esclarecimentos.1) a peça que cai é um ímã (bastante forte). A peça externa, ao que parece, é feita de cobre.2) Ímãs não atraem cobre (cobre não é ferromagnético, ao contrário do que a intuição comum pode sugerir).Então, porque o ímã é desacelerado quando cai pelo tubo de cobre?Isso acontece porque, com a queda do ímã, o campo magnético num ponto fixo a sua volta deixa de ser constante no tempo. Este campo variável gera correntes elétricas no material condutor (cobre). Esta correntes elétricas (de acordo com a Lei de Faraday-Lenz) irão gerar um campo magnético que se opõe à orientação do campo do ímã que cai. Ou seja, o movimento do ímã no interior do tubo transforma o tubo de cobre em um outro ímã com polaridade contrária à polaridade do ímã que cai. Por isso ele é freado.

- Qué pesado maricón?
- If you used a superconductor instead of copper, would the magnet hover?
