Norah Mcbride · Answer 1

Options (b) and (d) are correct about an electric motor.

Nola Leblanc · Answer 2

Options (b) and (d) are correct about an electric motor.

An electric motor is a device which coverts electrical energy into mechanical energy. It works on the principle that when a current carrying coil is placed in a magnetic field, it experiences torque. Because of that torque, the coil rotates and thus the electrical energy gets converted into mechanical (motion) energy.
