A magnet of dipole moment $2 A m^{2}$ is deflected through $30 °$ from magnetic meridian. The required deflecting torque is $(B_{H} = 0.4 \times 10^{- 4} T)$

Options:

Answer:

Solution:

When a magnet is placed in an external magnetic field it experiences torque

$τ = M B \sin θ$

$= 2 \times 0.4 \times 10^{- 4} \times \sin 30 °$

$= 0 .4 \times 10^{- 4} N m$
