Magnetic Constant


The magnetic constant, otherwise known as vacuum permeability, is the magnetic permeability in the vacuum. According to the Wikipedia definition, it is derived from the production of a magnetic field by an electric current or by a moving electric charge.

Waves travel in a medium, as illustrated in the next figure.  The magnetic constant represents the amount of “stuff” in a given length for this medium, better expressed as kilograms per meter.  When this stuff (referred to as granules in EWT) is contained in a particle as standing waves, it is truly measured in kilograms.  When it is traveling waves, it has been given the wrong unit and called a Henry.  The Henry can be resolved to kilograms when Coulomb charge is replaced with wave amplitude (see note on units below).

Derivation – Magnetic Constant

The magnetic constant is related to the inverse of the electric constant multiplied by c2. Thus, it is derived based on the value found in the electric constant. The removal of wave speed from the magnetic constant has significant meaning as it is no longer a force.  The units, which are derived below on this page, resolve to be the equivalent of a one-dimensional density.  The units are kilograms per meter.

The units are measured in kg/m compared with H/m for the magnetic constant, where H is Henries.  When Henries is derived in SI units to Coulombs and replaced with meters, the units resolve correctly to kg/m.

Its value was calculated and shown to match the known value in the Summary of Calculations table. The derivation of this constant is available in the Fundamental Physical Constants paper.
