Physics - Magnetism Question with Solution | TestHub

Two short bar magnets of length$1cm$each have magnetic moments$1.20 \mathrm{A} {\mathrm{m}}^2$and$1.00 \mathrm{A} {\mathrm{m}}^2$respectively. They are placed on a horizontal table parallel to each other with their$\text{N}$poles pointing towards the south. They have a common magnetic equator and are separated by a distance of$20.0 \mathrm{cm}$. The value of the resultant horizontal magnetic induction at the mid-point$\text{O}$of the line joining their centres is close to
( Horizontal component of earth's magnetic induction is$3.6\times {10}^{-5} \mathrm{Wb} {\mathrm{m}}^{-2}$)
