PURPOSE: To demonstrate the force between two adjacent parallel currents.
DESCRIPTION: The device uses two parallel currents, the lower one stationary and the upper one which can move to and away from the stationary wire. Current in the wires causes a force between the wires which can be determined by balancing the moving current loop with a movable counterweight. The measured magnitude of the force can be compared with the measured value.

EQUIPMENT: Current balance with power supply.
SETUP TIME: 5 min.
