In a generator, what happens to current when the conductor is not moving through the magnetic field?

In a generator, current is produced by electromagnetic induction, which depends on a changing magnetic flux as the conductor moves through the field. Faraday’s law says the induced EMF is proportional to the rate of change of magnetic flux. If the conductor isn’t moving, the magnetic flux through the loop doesn’t change, so the induced EMF is zero. Without EMF driving the current (in a closed circuit), no current flows. The other options would require a changing flux or an external source of energy, which isn’t present when there’s no motion.
