GEOLOGY

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: -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-3: -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.

Detailed explanation-4: -In an electric motor, the energy transformation is from electrical to mechanical.

Detailed explanation-5: -The most common device for changing electrical energy into mechanical energy is the motor. Most motors use electromagnets to cause mechanical rotation, which can do work.
