A rectangular loop of sides 10 cm and 5 cm carrying a current I of 12 A is placed in different orientations as shown in the figures below.
If there is a uniform magnetic field of 0.3 T in the positive z-direction in which orientations the loop would be in (i) stable equilibrium and (ii) unstable equilibrium?
(a) (a) and (b) respectively
(b) (a) and (c) respectively
(c) (b) and (d) respectively
(d) (b) and (c) respectively
