Homework Statement
A copper penny falls on a path that takes it between the poles of a magnet. Does it hit the ground going faster, slower, or at the same speed.
The Attempt at a Solution
Clearly the penny undergoes a change in magnetic flux. Since it receives a change in magnetic flux we expect that a current either begins within the penny, becomes stronger or reverses. Although there is a slight shift with the current it does not affect the mass of the penny or the effect of its gravitational constant. Because of this I expect there to be no change in velocity of the penny relative to the ground but a shift in velocity of current, I, within the penny. Is this correct?
