Inside most electric motors, the part that actually turns is the rotor. It holds the magnets or windings that become an electromagnet, and it spins inside the stationary magnetic field created by the stator. The stator stays fixed and provides the magnetic field that drives rotation, while the windings (the coil) are used to create that field. The term bell isn’t a standard label for a motor component, so it doesn’t fit as the rotating magnet. So the magnet that turns inside the motor is the rotor.
