Lenz’s Law – Magnet falling slowly in Copper Pipe Demonstration
If I learnt about Lenz’s Law in high school I must have forgot about it. Watch the cool demonstration above where a stack of neodymium ring magnets are dropped into a copper pipe. Of course copper is a non magnetic metal so the magnets will not stick to it. You would probably guess that the magnets would simply fall at the same rate as if they were just dropped. Well
