Induction motor stators have coils of wire placed in the center of the stator core, which form electro-magnets when energized and create magnetic pole fields.

Electro-Magnets

Devices that create a magnetic field when electric current flows through a coil wrapped around a metal core.

Magnetic Pole Fields

The regions at the two ends of a magnet where the magnetic force is strongest, known as the north and south magnetic poles.
