Explanation:
When the switch is off, then the momentum (angular) of the blades remains with the blades. Due to the friction acting on the blades at the center of the fan, the speed reduces slowly and gradually and then it comes to rest. Some energy in the fan wings is dissipated as heat due to friction.
