Two short bar magnets of length 1 cm each have magnetic moments `1.20A.m^(2) and 1.00A.m^(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 resultant horizontal magnetic induction at the mid - point O of line joining their centres is close to (horizontal component of earth's magnetic induction is `3.6xx10^(-5) "Wb " . m^(-2)` )
