1.	2 parallel co-axial circular coils have N turns carry a current i in each coil, in the same direction when seen from a point on common axis seen outside the space between the coils. The radius of each coil is R and they are seperated by 21.732R. The magnetitic induction at a the midpoint of the common axis is approximately - 1 Ni/31.73R 2 Ni/16R 3 Ni/8R 4 Ni/61.73R
