A circular coil having 13 turns and a radius of r 138 cm, Ask an Expert

Academics

A circular coil having 13 turns and a radius of R = 13.8 cm carries a current of 2.20 A. It is placed in a uniform magnetic field of 64.0 mT. The initial angle between the magnetic moment of the coil τ and the magnetic field B is 38.0^o.

Calculate the magnetic dipole moment of the coil.

What is the magnitude of the torque acting on the coil?

How much work is required to rotate the coil so that the B-field lies in the plane of the coil?
