Answer:

(C). The resistivity of the wire of the coil.

Explanation:

The magnitude of induced emf does not depend on the resistivity of the wire of the coil.

The magnitude of the induced emf produced when a magnet is moved into a coil depends on the rate of change of magnetic flux through the coil. I

t is given by Faraday's law of electromagnetic induction, which states that the emf induced in a coil is equal to the rate of change of magnetic flux through the coil. T

he induced emf is proportional to the rate of change of magnetic flux and does not depend on the speed with which the magnet is moved, the number of turns of the coil, the resistivity of the wire of the coil, or the strength of the magnet. However, the strength of the magnet does affect the magnetic flux and thus the induced emf. To maximize the induced emf, the magnet should be moved into and out of the coil as quickly as possible.
