seems like a young channel id love to see grow, already A tier videos. subbed. that thing where water boils if you vacuum it fast enough, cooling by boiling
No 7 Quick explanation The magnet moving near the copper causes a force that acts as a brake, slowing its natural motion down the pipe due to gravity. Where does the force come from? Electric currents and magnetic fields are closely related. If you have one, you often have (or can make) the other. The braking force in the demonstration is due to an eddy current. That's an electrical current that forms in the copper, in response to the moving magnetic field of the falling neodymium magnet. That eddy current produces a magnetic field of its own. The two magnetic fields overlap and slow the fall of the magnet. The science behind this braking force was described in the 19th century by physicist Heinrich Lenz
Thanks for the video! Every year I put on a big show for Halloween for the trick or treaters. I have done elephant toothpaste and iodine clock reaction and was looking for what to do this year. This was great. Might have a few years worth of ideas for me. Thanks!
