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?

Answer 1

NOTATIONS; mass M, Radius R, current R, uniform magnetic field B, and angle is theta.

Answer 2

current I
