11. The axial ratio is the ratio of the magnitudes of the major and minor axis defined by the electric field vector . 12. The magnitude of the force is given by the quantity of the charge multiplied by the magnitude of the electric field vector . 13. The out-of-equilibrium magnetization vector precesses about the external magnetic field vector at the NMR frequency of the spins. 14. If the wave is frozen in time, the electric field vector of the wave describes a helix along the direction of propagation. 15. With d \ mathbf l the element of path along the integration of electric field vector "'E " '. 16. They also do not show the direction of the field vector . talk ) 00 : 03, 4 October 2009 ( UTC) 17. Based on the properties of the cross product, this produces a vector that is perpendicular to both the velocity and magnetic field vectors . 18. Due to the interaction with the molecule, the electric field vector of the light traces out an elliptical path after passing through the sample. 19. Since the intensity or irradiance, I, of light is proportional to the square of the electric-field vector , the ellipticity becomes: 20. Each pair of magnetic rings forms a single effective magnet whose field vector can be fully and freely adjusted ( in both direction and magnitude ).
