Detailed explanation-1: -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-2: -The device is used to produce electricity is Electric Generator (DC).

Detailed explanation-3: -electric generator, also called dynamo, any machine that converts mechanical energy to electricity for transmission and distribution over power lines to domestic, commercial, and industrial customers. Generators also produce the electrical power required for automobiles, aircraft, ships, and trains.

Detailed explanation-4: -An ammeter is a device which is used to measure electric current through a circuit. Electric current is measured in amperes, hence the name ammeter.

Detailed explanation-5: -The galvanometer and ammeter are the devices used to measure the flow of electric current. They, however, do not generate any electric current themselves.
