Magnetic Force Accessory

This is an accessory for PASCO's Variable Gap Magnet. It includes three induction paddles, a current swing, a mounting rod (a standard lab stand is required) and two small rods (glass and aluminum). The paddles illustrate the production of eddy currents and the rods distinguish between paramagnetism and diamagnetism.
