Problem: You want to insert a loop of copper wire between the two permanent magnets in FIGURE. Is there an attractive magnetic force that tends to pull the loop in, like a magnet pulls on a paper clip? Or do you need to push the loop in against a repulsive force? Explain.

FREE Expert Solution

Copper is a non-magnetic material, thus it is not attracted by a magnet. 

However, when the loop of copper wire is inserted between the two permanent magnets, a current is induced in the loop.
