By driving the current through the wires in a particular direction, the resulting induced field forces the selected core's magnetic flux to circulate in one direction or the other ( clockwise or counterclockwise ).

If Cohen and Stixrude are right about the overall alignment of the iron, the inner core would have a single easy axis of magnetization _ a direction in which the induced field would be strongest.

The pulsed-power imparts electromagnetic fields into the cooling water and the induced fields have a direct effect in preventing mineral scale formation on equipment surfaces and controlling microbial populations to very low levels while also significantly reducing biofilms present in cooling systems.
14.
A full treatment would have to take into account the effect of the external and radiation-induced fields on the wave function of the electrons, and then calculate the effect of this change on the refractive index of the material for each polarization, to see whether the right-or left circular polarization is slowed down more.
15.
The physical interpretation of "'D "'is not as clear as "'E "'( effectively the field applied to the material ) or "'P "'( induced field due to the dipoles in the material ), but still serves as a convenient mathematical simplification, since Maxwell's equations can be simplified in terms of free charges and currents.
