• ID Code: K1-21
• 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 visible as a small rotation of the coil about its axis. Reversing the coil leads reverses the direction of the torque.

  A video camera can be made available upon request for displaying this demonstration in large lecture halls.
