Electromagnetic Induction 1. Connect the galvanometer, which measures current flowing in either direction in a circuit, to an 800-turn, 1600-turn, or 3200-turn coil. 2. Watch the current in the galvanometer as you move a bar magnet along the coil's axis as shown above. Observe the galvanometer during each of the following actions. Relate what you observe about the direction and amount of current in the coil while performing each action. Be specific without reporting numeric values. a. Change the speed of the magnet
