A student records the following data for the magnitudes (B) of the magnetic field at axial points at different distances x (See Figure 11 given below) from the centre O of a circular coil of radius a carrying a current I. Verify (for any two) that these observations are in good agreement with the expected theoretical values of B. (Application)

x	x = 0	x = a	x = 2a	x = 3a
B	$B_0$	$\frac{B_0}{2\sqrt{2}}$	$\frac{B_0}{5\sqrt{5}}$	$\frac{B_0}{10\sqrt{10}}$
