To keep the torque on a DC motor from reversing every time the coil moves through the plane perpendicular to the magnetic field, a split-ring device called a commutator is used to reverse the current at that point.

The split ring commutator is attached to the loop and conducts current into the loop by rubbing against the brushes. The brushes are usually carbon rods that carry current from the external power source to the commutator.

The difference between an AC and a DC generator is that the AC generator uses slip rings to transfer the current to the electrical circuit, while the DC generator uses a split-ring commutator. Generators can be very small or quite huge.
