Geometric Electro-Magnetic Field Equations for Particles with Charge and Spin

POSTER

Abstract

The complete and self-consistent "Maxwell" equations are displayed algebraically, describing (time-delayed} force and torque interactions between moving particles with charge and spin. The algebra is the 4-level Grassmann linear algebra describing 3D Euclidean space, starting from 4 independent points to generate structures for lines, planes, and volumes.



With this full algebra, two forces can add to become a torque, and two flows can add to become a circulation. With similar clarity, the algebra describes the motional (v/c) "transformations" between vector electric E and vortical magnetic B through simple motion of the 4th origin point, without "space-time algebra" effects. Thus, the algebra can explicitly distinguish between conduction currents and the orthogonal spin/circulation currents; and between dynamic effects such as spin-transfer torque, and entropic effects such as conduction resistance or magnetization damping.



Geometrically, the two fundamental lengths in electro-magnetism are the classical electron radius Re = e2/mec2 = 2.82 pm; and the "Compton wavelength" Dv = ħc /mec2 = 386 pm. Re scales the electric interaction energy between two charges, and Dv characterizes the vortical diameter (twice Bohr magneton) of a single electron spin. Significantly, a single propagating E-M wave necessarily links both together, with E = B in magnitude. Moreover, as a bi-vector, B squares to negative, making E2 + B2 = 0; and two oppositely propagating waves are required to transfer energy from one particle to another.



Understanding these geometrical structures can substantially clarify the complexity of probability wave function analysis.
