Two wires of equal lengths are bent in the form of two loops. One of the loops is square-shaped whereas the other loop is circular. These are suspended in a uniform magnetic field and the same current is passed through them. Which loop will experience greater torque? Give reasons.

Expert Answer:

The circular loop will experience greater torque  because it has larger area and hence greater magnetic moment.
