video - Force on a Current Carrying Wire in a Magnetic Field
Purpose:An illustration of the force exerted by a magnetic field on the moving charges in a current carrying wire.
Hang a single wire between the stands such that it passes between the poles of the horseshoe magnet at its lowest point. Connect the switch to the battery and to the base of the pole to which the hanging wire is attached. Depending on the orientation of the magnet and the direction of the current flow in the wire, when the switch is thrown the wire will either "jump away" from the magnet or be "pulled" into it.
