Question

3.11. A rectangular coil is freely suspended so that its vertical sides lie in a horizontal uniform radial field (ie. a field which is uniform in magnitude and radially directed in relation to the axis of rotation). Discuss the torque which acts on the conductor, using diagrams in your discussion. Derive an expression for the magnitude of the torque, and for the equilibrium angular displacement if the coil is free to rotate at the end of an elastic suspension.
