(a) What is meant by the torque acting on a current-carrying planar loop suspended in a uniform magnetic field?
(b) List any four physical quantities on which the magnitude of this torque depends.
(c) Keeping all other parameters fixed, qualitatively describe how the torque varies as the angle θ between the normal to the plane of the loop and the magnetic field is changed from 0 to π/2. Identify the orientations that give (i) maximum torque and (ii) zero torque.
