A bar magnet is falling through a loop of wire with constant velocity. The north pole enters first. The induced current will be greatest in magnitude when the magnet is located so that the loop is near the middle of the magnet. The loop is near either the north or the south pole. The loop is near the north pole only. A bar magnet is falling through a loop of wire with constant velocity. The south pole enters first. As the magnet leaves the wire, the induced current (as viewed from above) is clockwise along the length of the magnet. The induced current is counterclockwise. There is no induced current. According to Lenz's law, the direction of the induced current in a conductor will be that which tends to produce the effect which opposes the effect which produces it. It does not produce a greater heating effect or the greatest resistance.
