Question

Two identical short bar magnets, each having magnetic moment of  $$10$$ $$Am2$$, are arranged such that their axial lines are perpendicular to each other and their centres along the same straight line in a horizontal plane. If the distance between their centres is $$0.2m$$, the resultant magnetic induction at a point midway between them is μ$$0=4$$π x $$10-7$$ $$Hm-1$$
