    For a circular coil of radius R and N carrying current I, the magnitude of the magnetic field at a point on its axis at a distance x from its centre is given by B = (mu_0 I R^2 N)/(2(x^2 + R^2)^(3//2)) (a) Show that this reduces to the familiar result for field at the centre of the coil. (b) Consider two parallel co-axial circular coil of equal radius R, and number of turns N, carrying equal currents in the same direction, and separated by a distance R. Show that the field on the axis around the mid-point between the coils is uniform over a distance that is small as compared to R, and is given by , B = 0.72 (mu_0 N I)/(R) , approximately.
