Split-phase motors operate on the principle of a _____ magnetic field.

A) fixed
B) pulsating
C) vibrating
D) rotating

Split-phase Motors

A type of single-phase induction motor that uses a secondary start winding or auxiliary winding offset by electrical degrees to create a phase shift, helping to start the motor.

Pulsating Magnetic Field

A magnetic field that varies in amplitude over time in a periodic manner.

Rotating

The action or process of turning around a center or an axis; a fundamental movement in various mechanical and electrical devices.
