The plane of a rectangular coil of wire of dimensions `0.05 xx 0.10m` and carrying a current of 10 A ,is parallel to a magnetic field of 0.1 T . What is the torque on the coil? What will be the torque when the normal to the coil makes an angle of `30^(@)` with the direction of the field ?

Answer

`5 xx 10^(-13) N m; 2.5 xx 10^(-3) N m`
