Detailed explanation-1: -An electric motor converts electrical energy into rotational kinetic energy which is a form of mechanical energy. Electric motors are used in electric fans, pumps etc.

Detailed explanation-2: -Electric motors, which convert electrical energy into mechanical energy, are the most common application of magnetic force on current-carrying wires. Motors consist of loops of wire in a magnetic field. When current is passed through the loops, the magnetic field exerts a torque on the loops, which rotates a shaft.

Detailed explanation-3: -An electric motor is an electrical machine which converts the electrical energy into mechanical energy. So, the given statement-An electric motor converts mechanical energy into electrical energy is false.

Detailed explanation-4: -In an electrical motor, the energy transformation is from electrical to mechanical energy through the process of electromagnetic induction.

Detailed explanation-5: -A dc motor converts electric energy into mechanical energy. The principle on which it Is based is not mutual induction. A current carrying coil, in a magnetic field experiences a torque. This torque rotates the coil.
