Two coils each of 100 turns are held such that one lies in vertical plane and the other in the horizontal plane with their centers coinciding. The radius of the vertical coil is
0.20m and that of the horizontal coil is
0.30m. How will you neutralize the magnetic field of the earth at their common center? If the summation of current to be passed through each coil is
itotal=xA. Find x*10 .Horizontal component of earth's magnetic field=0.35×10−4 T and angle of dip=30o.
