Figure 1 is a sectional view of two circular coils with radius ?, each wound with ? turns of wire carrying a current ?, circulating in the same direction in both coils. The coils are separated by a distance ? equal to their radii. In this configuration the coils are called Helmholtz coils; they produce a very uniform magnetic field in the region between them. (a) Derive the expression for the magnitude ? of the magnetic field at a point on the axis a distance ? to the right of point ?, which is midway between the coils.
