When a magnet is moved into a coil connected to a galvanometer, the current is induced in the coil. The induced current does not depend on which of the following factor?

ANumber of turns of the coil

BThe pole strength of the magnet

CSpeed of movement of the magnet

DResistance of the galvanometer connected in the coil

Answer:

The induced current when a magnet is moved into a coil connected to a galvanometer does not depend on the resistance of the galvanometer connected in the coil.
While the induced electromotive force (EMF) itself is not directly dependent on resistance, the current flowing through the circuit is determined by Ohm's law, which states that current is equal to EMF divided by resistance.
Therefore, the magnitude of the current, and thus the deflection of the galvanometer, is affected by the resistance.
