A bar magnet is held vertically with its upper end a little bit below the center of a horizontal metal ring. The upper end of the magnet is its north pole. The bar magnet is now dropped. An observer views the ring from above its center. To this observer, how will the induced current in the ring behave as the magnet falls? (a)The current will flow clockwise and be increasing at first, and then eventually decreases as the falling continues. (b) The current will flow clockwise and be keeps decreasing as the falling continues. (c) The current will flow counterclockwise and will keep decreasing as the falling continues. (d) The current will flow counterclockwise and be increasing at first, and then eventually decreases as the falling continues. (e) The induced current will be zero.
