A student sets up the apparatus shown below to investigate electromagnetic induction.

A copper coil of wire is connected in a closed loop to a sensitive center-zero voltmeter. A bar magnet with marked North (N) and South (S) poles is held directly above the opening of the coil.

Explain how the student can use this apparatus to demonstrate the factors that affect both the size and the direction of the induced potential difference.
