If magnet was not rotated when dropped through the tube, would it simply stick to one wall in case of slightest imbalance?

- blacksmith_tb 13y agoCopper isn't ferrous, magnets can't stick to it.
- martinvol 13y agoI can't clearly remember my psychics class, But I think I'd fall a bit faster, as the movement through the pipe is considerable as well.
- kylek 13y agoThey used crystal balls instead of magnets in my psychics class :)
- dfbrown 13y agoI don't think the spinning should have any effect on the speed. Only the vertical movement would create eddy currents. It could be he does it to keep the magnet stable as it falls (like spin on a football).
- shawabawa3 13y agoIn the last drop he doesn't spin it and it seems to fall at the same speed, it also wobbles and hits the side, so I think you're right
- tedsanders 13y agoNo. Because copper isn't ferromagnetic, it will not be magnetized by the magnet, and consequently the magnet and the copper will not be attracted to each other. (In fact copper is diamagnetic, so it will actually slightly repel.) Source: I am a magnet scientist.
- Shish2k 13y ago> I am a magnet scientist. Judging entirely by the name, that sounds awesome :D What do you do all day?
- tedsanders 13y agoA lot of reading, plumbing, and electrical work. But when things are running smoothly, we grow complex oxide crystals using pulsed laser deposition and then measure their magnetism with SQUIDs (superconducting quantum interference devices).
- Angostura 13y agoSo what would happen, minus the spin - straight through at roughly G?
