Operation
Hook the leads from the galvanometer to the induction coil. Place a magnet in front of the coil. Turn the crank and the needle on the galvanometer should move. The connection between the galvanometer and the loop changes polarity every half turn.
Safety
Magnet is extremely strong so do not place metal objects near it.

A galvanometer is activated by placing a magnet near an induction coil and rotating the induction coil.
