Question

The rotational effect experienced by a current-carrying loop placed in a uniform magnetic field is called:

विकल्प

• torque

• electromotive force

• magnetic flux

• magnetic dipole moment

Answer 1

Torque is defined as the rotational effect experienced by a current-carrying loop placed in a uniform magnetic field. For a coil of N turns, its magnitude is \[\tau = NIAB\sin\theta\].
