[SOLVED] Nasty Physics Assignment I was given this question by my physics teacher "You were shown a demonstration whereby two cylindrical slugs of metal were allowed to free-fall down a hollow vertical tube made of copper. One of the slugs, a magnet, took significantly longer to fall through the tube than the other. Why? (i) Describe what you saw and try and explain why the fall times were different. Use the principles described in the lectures to help you. (ii) Can you think of a possible application for this effect? You may have to go to the library to find the answer. Minimum length should be one A4 page. A Clue: Eddy current." Does anyone have any idea what eddy currents has got to do with the result of this experiment???? Thanks!!!!
