Expert Solution
Introduction:

When a current carrying rectangular coil is kept in presence of magnetic field, it experiences a torque. The net force on this rectangular coil is zero but there is a net external torque. This torque is given by

τ=BINAsinθ

Where N,I are number of turns in coil and current in coil respectively.

B,A are the uniform magnetic field and area of coil respectively.
