The magnetic field at a point,

The magnetic field at a point, $10 \mathrm{~cm}$ away from a magnetic field dipole, is found to be $2.0 \times 10^{-4} \mathrm{~T}$. Find the magnetic moment of the dipole if the point is

(a) in end-on position of the dipole and

(b) in broadside-on position of the dipole.
