Do consider that one can run a current though a wire, and one can oscillate the amount of current. In another wire some distance away this current oscillation will appear! This phenomenon is called "light" and has been extensively studied over an amazing range of frequencies. There is no other phenomenon that so perfectly obeys the linear wave equation over such a dynamic range.

Please start treating your hosts with at least a little respect and find somewhere else to publish your thoughts.

Torque ... is a tangential or orthogonal force. In this case, tangential and orthogonal both just mean the force is at a right angle. If we let our spinning object [i.e. photon] travel, a force at the forwardmost point on the [photon] will be orthogonal to the line of motion. Since [a photon] moving forward would be most likely to hit another particle at or near the forwardmost point, [the photon] moving forward is most likely to transmit angular momentum as an orthogonal force. This is why the magnetic field is orthogonal to the electrical field. One is caused by linear motion, and the other is caused by the spin on the particle in linear motion. The forward motion of the photon causes the electrical force or field, the spin of the photon causes the magnetic force or field.

photon A continues straight ahead, because of momentum and other photons on a parallel path
"One of the wildest things we did was to make the electrons think they are in a huge magnetic field when, in fact, no real field had been applied,"Manoharan said.... to make its electrons believe they were being exposed to magnetic fields ranging from zero to 60 Tesla, more than 30 percent higher than the strongest continuous magnetic field ever achieved on Earth.
Their first examples, reported today in Nature ("Designer Dirac fermions and topological phases in molecular graphene"), were hand-crafted, honeycomb-shaped structures inspired by graphene, a pure form of carbon that has been widely heralded for its potential in future electronics. Initially, the electrons in this structure had graphene-like properties; for example, unlike ordinary electrons, they had no mass and traveled as if they were moving at the speed of light in a vacuum.
To tune the electrons' properties, the researchers repositioned the carbon monoxide molecules on the surface; this changed the symmetry of the electron flow

In experiments, Dr Branford applied an electrical current across a continuous honeycomb mesh, made from cobalt magnetic bars each 1 micrometer long and 100 nanometres wide, and covering an area 100 square micrometers (as pictured). A single unit of the honeycomb mesh is like three bar magnets meeting in the centre of a triangle. There is no way to arrange them without having either two north poles or two south poles touching and repelling each other, this is called a 'frustrated' magnetic system. In a single triangular unit there are six ways to arrange the magnets such that they have exactly the same level of frustration, and as you increase the number of triangular units in the honeycomb, the number of possible arrangements of magnets increases exponentially, increasing the complexity of possible patterns.
Previous studies have shown that external magnetic fields can cause the magnetic domain of each bar to change state. This in turn affects the interaction between that bar and its two neighbouring bars in the honeycomb, and it is this pattern of magnetic states that Dr Branford says could be computer data.
