When a conductor is moving in a constant magnetic field, the voltage will be induced as per the Faraday's first law, which results in in-turn induces a current.
But current direction reverses as the conductor is moving back and forth, hence voltage polarity also reverses.

It occurs in AC circuits, as this is the principle of ac cycle.
