Which component is stationary and houses the magnetic field in many electric machines?

• A. Rotor
• B. Stator
• C. Armature
• D. Field coil

Answer: (B)

The stator is the stationary part that surrounds the rotor and houses the windings or permanent magnets that generate the magnetic field. This field interacts with currents in the rotor to produce torque as the machine runs. The rotor is the rotating part inside, while the armature refers to the winding carrying current or hosting induced voltages, and the field coil is simply the winding that creates the magnetic field (often placed on the stator in many designs).
