Force on a Conductor Apparatus

A version of traditional piece of equipment for demonstrating the effect of current flowing through conductor in the presence of magnetic field. Connection is made via the 4 mm sockets attached to the side rails. When current of up to 8 A flows, the crossbar rolls one way or the other under the action of the electro-magnetic force. With clearly labelled poles to the magnet it is easy to demonstrate Fleming's Left Hand Rule.
