Two short bar magnets have magnetic moments `1.20 " Am"^(2)` and `1.00 " Am"^(2)` , respectively .
They are kept on a horizontal table parallel to each other with their north 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 midpoint O of the line joining their centers is ( Horizontal components of Earth's magnetic induction is `3.6 xx 10^(-5) Wb m^(-2)`).
