The coiling force-field of White Light transforms your aura into an electromagnet, giving you a certain degree of strength. The number of turns. An increase of turns in a coil increases the magnetic strength of the coil. If you increase the amount of current in a coil, the magnetic strength increases. The core of the coil is the material within the coil.
Permeability is the ability of a substance to conduct magnetic lines of force easily.
The spinning electromagnetic force-field of light has a transmuting, purifying effect. Recording studios, radio and TV stations have what they call a bulker. It is a large electromagnet which is passed over a tape in order to erase any sound previously recorded. In this way the tape is cleaned, cleared, ready to be used again. You can, in effect, bulk your aura by visualizing the Light.
