    b. Repeatedly reverses the flow of current through the armature.

    Explanation:

    The electric motor is a device that converts the electrical energy into mechanical energy. The commutator is a device that repeatedly reverses the flow of current through the armature. It is a split ring that acts as the commutator. It connects the external circuit through a carbon brush and the armature of the motor. Another important component of an electric motor is an electromagnet or permanent magnet.
