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 zto 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/2πε0(z– d/2)3and the field produced by the left dipole is –qd/2πε
