A bar magnet is held vertically above a horizontal metal ring, with the south pole of the magnet at the top (Figure 22.63). If the magnet is lifted straight up, will current run clockwise or counterclockwise in the ring, as seen from above?

A bar magnet is oriented above a copper ring, as shown in the figure. The magnet is dropped and passes completely through the ring. As viewed from above, what is the direction of the current induced in the ring after the magnet has completely passed through the ring and is somewhat below it? There is no current in the ring. counterclockwise clockwise

For each of the actions depicted below, a magnet and/or metal
loop moves with velocity v? (v? is constant and has the same
magnitude in all parts). Determine whether a current is induced in
the metal loop. If so, indicate the direction of the current in the
loop, either clockwise or counterclockwise when seen from the right
of the loop. The axis of the magnet is lined up with the center of
the loop.
