Question

(a) State Biot-Savart's Law. Use it to find the expression for magnetic field at the centre of a circular loop of current. (b) A circular loop of radius r, having N turns and carrying current I, is kept in the XY plane. It is then subjected to a uniform magnetic field B=Bxi+ Byj+ Bzk. Obtain expression for torque experienced by the coil.
