What Happens When You Drop A Magnet Inside A Copper Tube… (via Digg)
I was eating a sandwich and about 3/4 of the way through the video I realized I had stopped chewing and was just sitting there with the food in my mouth in awe of what I was watching. I may have forgot to breathe too
I cannot for the life of me remember the name of the phenomenon, but it has to do with changing magnetic flux as the magnet moves through the tube due to gravity, and an induced magnetic field being generated to oppose that change in flux. Thus, the magnetic force resisting gravity.
(I’m a little fuzzy on this, naturally. Feel free to correct me :V)
Did you mean: Lenz Law and electromagetism?
I was giggling like a little girl the entire video.
