Rotating Magnetic Fields in Induction Motors

Induction motors work by exploiting the principle of electromagnetic induction. A rotating magnetic field gets generated within the motor's stator windings. This rotating field creates a current in the rotor windings, which in turn produces a magnetic field. The interaction between these two fields leads to a torque that drives the motor shaft.

Several aspects influence the magnitude of the rotating magnetic field, including the number of poles, winding configuration, and supply voltage. A higher electrical potential generally leads to a more intense rotating magnetic field.
