First period test 1. How are speed and direction of magnet movement related to the induced current in the wire? 2.How can you use the idea of induction to produce continuouse voltage/current? 3.If a compass needle is a small magnet, why does the north end of the needle point toward the north pole and not to the south pole? 4. What makes the rotar spin in a DC motor?
