Physics - Magnetism Question with Solution | TestHub

Two short magnetic dipoles $m_1$ and $m_2$ each having magnetic moment of $1 \mathrm{A} {\mathrm{m}}^2$ are placed at point $O$ and $P$ respectively. The distance between $OP$ is $1 \mathrm{m}$. The torque experienced by the magnetic dipole $m_2$ due to the presence of $m_1$ is $\_\_\_\_\_\_\_\_\times {10}^{-7}\mathrm{N} \mathrm{m}$
