The Laplace Force Apparatus helps in measuring the force on a conductor in a magnetic field. The Laplace Force Apparatus consists of a powerful U shaped magnet, a pair of brass rails complete with 4mm sockets, and a brass axle. There is a power supply unit connected to the rails and when the axle is placed on them, the electric circuit is completed which results in the axle being repelled along the rails. Either the direction is towards or away from the magnetic field, and reversing the current will have the opposite effect.
