Question

A circular coil of N turns has radius R, and carries a currenrt I in the counterclockwise direction in each turn. The coil lies in the wy-plane,with its center at the origin. There is a uniform magnetic field B=B_xi + B_zK everywhere. Assume both B_x>0 and B_z>0.

(a) What is the net force on the coil? Remember that the magnetic field is uniform.

(b) Find the magnetic dipole moment μ of the coil.

(c) Find the torque vector on the coil.
