Lenz's Law (501-10)
Consists of two metal rings connected by an aluminum beam that can rotate freely on a support. One of rings is a closed loop, the other has an opening for comparison. When a bar magnet moves into or out of the loop the magnetic flux will change. According to Lenz's Law, a current will be induced in the loop to oppose the change. Students can verify the law by analyzing the movement of the loop. Comes with a comprehensive activity manual.
