A circular wire loop of mass and radius carries a current . It hangs from a hinge that allows it to swing in the direction perpendicular to the plane of the loop. A uniform magnetic field exists everywhere in space pointing upwards. What angle does the plane of the loop make with the vertical when it is in static equilibrium?

Question

A circular wire loop of mass   and radius   carries a current  . It hangs from a hinge that allows it to swing in the direction perpendicular to the plane of the loop. A uniform magnetic field   exists everywhere in space pointing upwards. What angle   does the plane of the loop make with the vertical when it is in static equilibrium?
