What is pulsating magnetic field?
Answer
A magnetic field that oscillates in magnitude along a fixed axis without rotating.
A Pulsating Magnetic Field is a magnetic field that remains stationary in space (its axis does not rotate) but varies sinusoidally in magnitude and reverses polarity over time.
This type of field is typically produced by passing a single-phase alternating current through a single stationary winding.
