Question

Which two statements about an electric motor are true?

a.It converts motion energy to electric energy.

b.It depends on the relative motion of a magnet and a current-carrying wire.

c.It depends on a rotating magnet to create a magnetic field.

d.It converts electric energy to motion energy.

e.It doesn’t require electricity because it uses electromagnetism.

Answer 1

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.

Answer 2

Answer:

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