A generator turns motion into electricity. A DC motor turns electricity into motion.
In a generator, spinning a coil in a magnetic field induces voltage. Connect a circuit, and current flows.
In a DC motor, current in a coil interacts with a magnetic field, producing rotation. In a brushed motor, a commutator reverses the coil’s current every half turn, keeping it spinning.
