Question

A circular coil of 100 turns and effective diameter 20 cm carries a current of 0.5

a. It is to be turned slowly in a magnetic field b = 2t from a position in which the angle between normal to the coil and the magnetic field i.E. Equals to zero to equals to 180°. The work required in the process is :

Answer 1

Since work done is equal to change in energy.
So evaluate MBcos0°-MBcos180° .
So net work done is 2π J .
