Question

It. Summary questions below, in which you moved the bar magnet toward the coil, with the north pole facing the eo. None Direction of Suppose chat you repeated this situation with single change made to the apparatus For each single Suppose that you change described below . Would that change cause the maximum EME induced in the coil to be greater than, smaller than or the same as what it was in the original situation? Would that change cause the maximum deflection of the galvanometer needle to be greater t smaller than, or the same as what it was in the original situation? 2. Explain your reasoning. Case #l: The speed at which you moved the magnet is larger than what it was on speed at which you moved the magnet is larger than what it was originally. Case coil 2: One of the wires to the galvanometer is cut just before you move the magnet toward the

Explanation / Answer

1. the maximum EMF will be GREATER THAN what was induced in the coil previously.With North pole moving towards the coil, more flux will be passing through the coil as the bar moves closer to the coil.

2. The deflection in the coil will be greater than original situation.

Case#1: More the speed, more EMF generated than the original case.

Case#2: No change or no deflection in galvanometer if the wire is cut before the magnet is moved towards the coil.
