Your question is ill-phrased and I have difficulty answering it. You are correct that moving a magnet through a copper coil should produce a current, by magnetic induction. However, current is measured in units of amperes (1 A = 1 C/s). Volts are a measure of electric potential or potential energy per charge (1 V = 1 J/C). The amount of current driven by the 1.5V potential of a battery/power supply depends on the resistors (and inductors, if AC) in the circuit. Talking about generating "1.5V of electricity" I suspect means you are thinking of replacing a 1.5V battery or power supply with the moving magnet. A moving magnet will stop inducing current in the wire when it stops moving, so you will likely have to move the magnet in and out of the coil cyclically. This means you will induce a current in one direction, then another... that is you would be generating alternating current. Most motors I am aware of require direct current... which is difficult to generate in the scheme you describe.
