Two short bar magnets of length $\displaystyle 1$ cm each have magnetic moments $\displaystyle 1.20 \mathrm{Am}^2$ and $\displaystyle 1.00 \mathrm{Am}^2$ 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 $\displaystyle 20.0$ cm. The value of the resultant 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 $\displaystyle 3.6 \times 10^{-5} \mathrm{~Wb} / \mathrm{m}^2$ )
