The AC’s capacitor creates a leading current in the motor’s start winding. The leading current creates a rotating magnetic field that makes the motor start spinning. Once the field is built, current can flow normally through the wire. When the switch gets opened, the magnetic field around the coil keeps current flowing in the coil until the field collapses. This current keeps the bulb lit for a period of time even though the switch is open. In other words, an inductor can store energy in its magnetic field ...
