Force on a Conductor Apparatus
Connection is made via the 4mm sockets attached to the side rails.
When a current of up to 8A flows the crossbar rolls one way or the other under the action of the electro-magnetic force.
This is a traditional piece of equipment for demonstrating the effect of a current flowing in a conductor in the presence of a magnetic field.
Low voltage bench PSU required.
With clearly labelled poles to the magnet.
