Question

A circular coil of 100 turns and having an effective radius of 5cm carries a current of 0*1 ampere. How much work is required to turn it in an external magnetic field of 1*5 weber//m^2 through 180^@ about an axis perpendicular to magnetic field. The plane of the coil is initially perpendicular to the magnetic field.

A circular coil of 100 turns has an effective radius of 0.05 m and carries a current of 0.1 A. How much work is required to turn it in an external magnetic field of 1.5Wbm-2 through 180∘ about an axis perpendicular to the magnetic field. The plane of the coil is initially perpendicular to the magnetic field.
