An electric motor is a device that transforms:

The correct answer is: Electrical energy into mechanical energy

• Electric motors make mechanical energy through the interaction between magnetic fields.
• 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. Electrical energy is converted to mechanical work in the process
• Electric motor is a device which converts electrical energy into mechanical energy.
