A Helmholtz coil has a pair of loops, each withN turns and radius R. They are placed coaxially at distance R and the same current I flows through the loops in the same direction. The magnitude of magnetic field at P, midway between the centres A and C, is given by [Refer to figure given below]: ltimg src=\"https://d10lpgp6xz60nq.cloudfront.net/physics_images/JM_18_PHY_P3_E01_026_Q01.png\" width=\"80%\"gt
