GEOLOGY

Detailed explanation-1: -An electric motor converts electric energy into mechanical energy that can be used to do work. Each time the current flow is reversed in the wire, the electromagnet moves in response to the repelling force of like poles and the attracting force of unlike poles.

Detailed explanation-2: -Hence, a device which converts electrical energy into mechanical energy is called a motor.

Detailed explanation-3: -An electric motor is a device that uses an electromagnet to change electrical energy to kinetic energy. When current flows through the motor, the electromagnet rotates, causing a shaft to rotate as well. The rotating shaft moves other parts of the device.

Detailed explanation-4: -An electric motor is an electrical machine that converts electrical energy into mechanical energy. Most electric motors operate through the interaction between the motor’s magnetic field and electric current in a wire winding to generate force in the form of torque applied on the motor’s shaft.

Detailed explanation-5: -The basic function of a generator is to convert mechanical energy into electrical energy. A simple electric generator is shown in the figure on the right. Mechanical energy is needed to rotate the coil of wire located between the pole faces of a permanent magnet.
