In an electric motor,  Brush remains fixed and Commutator rotates with the coil.

Explanation:

The carbon brushes remain unchanged to the motor base, while the Commutator (separated rings) is rotating.

Commutator :-

  • A DC motor's operating principle is based upon the interaction between a rotating armature's magnetic field and a fixed stator's magnetic field.
  • As the armature's north pole is drawn to the stator's southern pole (and vice-versa), a force is exerted on the armature, which causes it to move.
  • Switching is the process of changing the field in the armature windings to generate constant torque in one way, and the switch is an armature-connected device that allows the current to be switched.
