The figure shows an arrangement known as a Helmholtz coil. It consists of two circular coaxial coils, each of N = 167 turns and radius R = 23.2 cm, separated by a distances = R. The two coils carry equal currents i = 10.2 mA in the same direction. Find the magnitude of the net magnetic field at P, midway between the coils. Number i Units -0.0 R -s
