The Proximity Effect

The proximity effect can be explained conventionally by magnetic fields inducing eddy currents in a conductor causing the wires to carry their currents either on the inside of the conductor or on the outside of the conductor. The wires will either repel each other or attract each other.

Alternatively we can look at the dielectric field flux. The escaping electrons from the conducting conductor will eddy out quickly behind surrounding molecules in the dielectric material. Other electrons will continue on eddying out eventually to spin with a much larger radius. If this eddy effect reaches the return conductor, and it will, it will cause an additive current effect on the inside of the conductor. We see the proximity effect due to eddy currents in the dielectric.

At the same time we note the tight circular spinning and the large circular spinning in the dielectric. This may be measured as a decrease in the electric field between the conductors. Really the electrons are efficiently spinning, briefly, without associated positive charge. Very quickly, and some might say instantaneously positive ions rush in to balance the charge. The positive ions, too, will spin in a spatially efficient manner. The effect is more matter spinning between the wires forcing them apart.

When we get talking about inductance and spinning electrons or spinning molecules some people love to get hung up on vortexes. While I am certain vortexes will be shown to play a huge part in inductance and the proximity effect it is most important to focus on the efficiencies of matter organizing itself in a spinning manner. Think about the bottom of a tornado.
