Two short bar magnets of length 1 cm each have magnetic moments 1.20 Am 2 and 1.00 Am 2 respectively. They are placed on a horizontal table parallel to each other with their N poles pointing towards the South. They have a common magnetic equator and are separated by a distance of 20.0 cm. The value of the result and horizontal magnetic induction at the mid - point O of the line joining their centers is close to (Horizontal component of earth’s magnetic induction is 3.6× 10 –5 Wb/m 2 )
