Magnetostatic analog for the calculation of phase contours inelectron holography of magnetic films

A method is presented for predicting the electron holographic interference pattern from a given magnetization distribution, and it is explained how phase contours can be sketched using magnetostatic intuition. The presented method is derived from the classical Lorentz force and the de Broglie relation between momentum and wavelength. The calculation of the electron phase to a two-dimensional magnetostatics problem is also mapped to which engineering experience and familiar mathematical methods can be applied. The result is considered simple to state and to remember
