Two short bar magnets of length 1 cm each have magnetic moments 1.20 Am^2 and 1.00 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 separted by a distance of 20.0cm. 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 earths magnetic induction is 3.6 × 10.5 Wb/m^2

A small coil C with N = 200 turns is mounted on one end of a balance beam and introduced between the poles of an electromagnet as shown in figure. The cross sectional area of coil is A = 1.0 cm^2, length of arm OA of the balance beam is l = 30 cm. When there is no current in the coil the balance is in equilibrium. On passing a current I = 22 mA through the coil the equilibrium is restored by putting the additional counter weight of mass Δm = 60 mg on the balance pan. Find the magnetic induction at the spot where coil is located.
