Two short bar magnets of length 1cm each have magnetic moments 1.20Am2 and 1.00Am2 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 20.0cm. The value of the resultand horizontal magnetic induction at the mid-point O of the line joining their centres is close to (Horizontal component of earth.s magnetic induction is 3.6×10.5Wb∕m2 )

3.6×10.5Wb∕m2
2.56×10.4Wb∕m2
3.50×10.4Wb∕m2
5.80×10.4Wb∕m2
