Two short magnetic dipoles $\displaystyle \mathrm{m}_1$ and $\displaystyle \mathrm{m}_2$ each having magnetic moment of $\displaystyle 1 \mathrm{Am}^2$ are placed at point O and P respectively. The distance between OP is $\displaystyle 1$ meter. The torque experienced by the magnetic dipole $\displaystyle \mathrm{m}_2$ due to the presence of $\displaystyle \mathrm{m}_1$ is \_\_\_\_ $\displaystyle \times 10^{-7} \mathrm{Nm}$.
