Medium$A$ short bar magnet of magnetic moment $2.5 \text{ Am}^2$ is kept in a uniform magnetic field of $4 \times 10^{-5} \text{ T}$. The work done in moving the magnet from its most stable position to its most unstable position is:
- A$40 \times 10^{-5} \text{ J}$
- B$25 \times 10^{-5} \text{ J}$
- C$10 \times 10^{-5} \text{ J}$
- D$20 \times 10^{-5} \text{ J}$

DifficultAP EAMCET 2020
View Solution$A$ magnetic dipole is under the influence of two orthogonal magnetic fields, $B_1 = 0.5 \times 10^{-3} \ T$ and $B_2 = 0.866 \times 10^{-3} \ T$. If the dipole comes to stable equilibrium at an angle $\theta$ with respect to the $B_2$ field, then the value of $\theta$ is (in $^{\circ}$)
