- To show that the current is induced in a coil when magnetic lines of force cut the conductors.
Terminals of the coil are connected to an overhead projection galvanometer. The assembly is set up on the O.H. projector in its entirety and the O.H.P. is focussed on the meter scale. Inserting a magnet will produce a deflection on the meter in one direction. motionless magnet will bring the pointer to zero. Retraction of the magnet will deflect the meter pointer in the opposite direction.
