In terms of the egs system, the unit of electron charge (and quantity) is calculated by multiplying the Faraday constant by the mass equivalent of unit atomic weight:

2.89366x10^{14} esu/g-equiv * 1.65979x10^{-24} g = 4.80287x10^{-10} esu

(ref. [1]). Of course, 4.80287x10^{-10} esu is equal to 1.602062x10^{-19} coulombs.

In space-time terms, the dimensions of electron charge (or electric charge in general) are t/s. The magnetic charge is a two-dimensional form of the electric charge; its space-time dimensions are t^{2} /s^{2} . The numeric value of the magnetic charge must therefore be the value of the electric charge divided by the the natural value of s/t, or the speed of light. In the egs system, this results in

4.80287x10^{-10} esu / 2.99793x10^{10} cm/sec = 1.602062x10^{-20} “esu”

(ref. [2]). The “esu” here are the *magnetic* units of the electrostatic system. According to ref. [3], 1 “esu” of magnetic flux (equivalent to charge in the Reciprocal System) equals 299.8 webers. Thus one unit of magnetic charge equals 4.802982x10^{-18} webers.

Each atom has two rotating systems; if one system acquires a magnetic charge, the other system must also acquire a charge if there is to be stability and permanence. Henee each atom has two poles, or centers of magnetie effect--it is dipolar, not monopolar.

Consider a simple “bar magnet” of four iron atoms. The poles would be arranged in this manner: N-S - N-S - N-S - N-S. Only the end atoms are not neutralized; therefore, in general only the surface atoms of a bar magnet contribute to its effective magnetic charge (one unit of charge per surface atom). This means that it would take 2.0820399x10^{17} magnetically charged surface atoms to generate one weber of magnetic flux. Since iron has a mean atomic weight of 55.847, the total mass of these surface atoms would come to 1.9301763x10^{-5} grams.
