# Fundamentals of Electro- and Magneto-Optics and Non-Linear Optics

Chapter

## Abstract

Linearity implies a limitation on the strength of the electric field in the electromagnetic wave. For moderate field strengths, the electric interaction is much stronger than the magnetic. Thus the ratio of magnetic to electric force on an electron subject to a “free space” e-m field is given by where F is the magnitude of the Poynting vector. For the visible region of the spectrum this ratio is of the order 10

$$\frac{Magnetic force}{Electric force} = \frac{e^{2}F}{2m^{2}\omega ^{2}c^{3}\varepsilon_{0}}$$

^{-23}F where F is in watts/m^{2}. Thus for any but the highest power fluxes, the magnetic interaction is negligible.## Keywords
