Purpose: Demonstrates the torque on a current loop in a magnetic field
Description: A few-turn coil is positioned in the magnetic field of a small horseshoe magnet as shown in the photograph. Pushing the switch connects the battery to the coil, passing electrical current through the coil and creating the torque, which is clearly visible as rotation of the coil about its axis. Reversing the coil leads reverses the direction of the torque.
