Q.

Two identical short bar magnets each having a magnetic moment of $10{\mathrm{Am}}^2$, are arranged such that their axial lines are perpendicular to each other and their centres are along the same straight line in a horizontal plane. If the distance between their centres is $0.2\mathrm{m}$, What is the resultant magnetic induction at a point midway between them? $\left({\mu }_0=4\pi \times {10}^{-7}\mathrm{H}/\mathrm{m}\right)$.
