magnitude p = qd . The moments point in opposite directions and produce fields in opposite directions at points on the quadrupole axis. Consider the point P on the axis, a distance z to the right of the quadrupole center and take a rightward pointing field to be positive. Then, the field produced by the right dipole of the pair is qd /2 πε 0 ( z d /2) 3 and the field produced by the left dipole is – qd /2 πε
