Question

in an electric motorhow and why does the magnetic field cause the coil of wire to rotate?

Answer 1

The working principle of electric motor is based on the magnetic effects of current. When a current carrying coil is placed in a magnetic field, the coil rotates because a force acts on it. When the coil rotates, the shaft attached to it also rotates. This is the process by which an electric motor converts electrical energy into mechanical energy.
