Detailed Solution

The electrical fan is a device that utilises the magnetic effect of electric current.
Electric fans contain an electric motor in them. Electric motors consist of a current-carrying coil and magnets. Magnets provide the magnetic field. So when the magnetic field of magnets and the magnetic field produced by the current-carrying coil interact, a force acts on the coil, due to which it rotates. On the other hand, the electric heater, bulb, and electric iron are the appliances that utilise the heating effect of electric current.
