Eddy Currents

An electric motor is the device that uses slip rings to reverse the direction of current through the coil. This reversal of current direction is essential for the continuous rotation of the motor. The slip rings are part of the commutator system within the motor, which serves to periodically reverse the current direction in the coil as it rotates. This ensures that the torque acting on the coil always acts in the same rotational direction, facilitating the motor's operation.
