A rectangular coil is hung in a uniform magnetic field such that the angle between the coil’s normal and the field is gradually changed. At which of the following orientations will the coil experience maximum torque?
(a) When the coil’s plane is perpendicular to the magnetic field
(b) When the coil’s normal is antiparallel to the magnetic field
(c) When the coil’s normal is perpendicular to the magnetic field
(d) When the coil’s plane makes an angle of 45∘ with the magnetic field
