Question 235: Magnetism and Matter

Question

A rectangular loop of sides $$10$$ $$cm$$ and $$5$$ $$cm$$ carrying a current $$1$$ of $$12A$$ 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 ?

Accepted Answer

For stable equilibrium $$\mathop M\limits^ 	o  ||\mathop B\limits^ 	o  $$
For unstable equilibrium $$\mathop M\limits^ 	o  ||\left( { - \mathop B\limits^ 	o  } ight)$$

Answer
