An electric toothbrush works by vibrating and oscillating. The motion is usually caused by an electric charge produced by a small battery in the toothbrush. Some electric toothbrushes work by inductive charging, which is when two parts of a transformer inside the brush are brought together and a small magnetic field creates an electric current to charge the battery. Other electric toothbrushes are operated by disposable, replaceable or rechargeable batteries. The electronic compartments of the toothbrushes are sealed to prevent water from seeping in and damaging the product.

When you recharge your toothbrush, the coil supplies electric flux. The electric flux recharges the battery in the toothbrush.
When you turn on the electric toothbrush, the electric flux flows from the battery to the motor, which converts electric energy into mechanical movement.
