The magnetic field at a point, 10cm away from a magnetic dipole, is found to be 2.0 x 10-4T. 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.
B = 2 × 10–4T
d = 10cm = 0.1m
(a) if the point at end-on postion.
(b) If the point is at broad-on position
