Solution :
| [a] is in stable equilibrium because \[i\vec{A}\] and \[\vec{B}\]are in same direction is in unstable equilibrium \[i\vec{A}\]and \[\vec{B}\] are opposite in direction |
| 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 ? |
