electromagnetic interaction, or electromagnetic force,
a long-range force involving the electric and magnetic properties of
ELEMENTARY PARTICLES. It is responsible for the repulsion of like and
attraction of unlike electric charges and explains atomic structure
and the properties of LIGHT and other
forms of ELECTROMAGNETIC RADIATION. The electromagnetic interaction is
mediated, or carried, by PHOTONS.
Because its effects can be easily observed, electromagnetism is the
most thoroughly studied and best understood of the four fundamental
forces of nature. The same laws that govern electromagnetism on the
subatomic scale also apply on a large scale in motors, generators, and
electronic equipment. A moving electric charge gives rise to a
magnetic field, and if its motion changes the magnetic field varies
and in turn produces an electric field; this is the origin of
electromagnetic radiation. Electromagnetic fields are generated by
electric motors and household appliances and by power transmission
lines. It has been suggested that such fields, particularly those
around transmission lines, may cause or promote childhood cancer. A
number of studies have been conducted, but the results are
contradictory and a generally accepted link has not been established.

Whatever media we want to talk about, whether the Internet or television or radio, it all rests on two forces, which are the electricity which powers the thing and the electromagnetic universe which we exploit in a variety of different ways in order to produce our mediated world. These are very much the lifeblood of the media sphere: both electric power and the electromagnetic spectrum. These things are so ordinary to us that they are just part of the furniture. Superficially, they seem devoid of anything strange or uncanny. But this is not entirely the case. It is certainly the case that, while we take for granted both electricity and the electromagnetism we exploit for radio and television signals, they are actually very strange things. The more you try to understand the signs behind it, the more you realize how bizarre and counterintuitive they are. We take them for granted because the stuff works very well and very obviously. But of the kinds of things we encounter in our ordinary day-to-day lives---you know we don't run into quantum physical phenomena directly very often, but we do bump into electricity and electromagnetism all the time---they are quite strange if you think about it.

R.O. Becker, author of Cross Currents, has contributed a thought-provoking article on the mechanisms by which humans perceive the cosmos. From the many stimulating ideas he presented, we select his rationale for believing that an electromagnetic basis may exist for the reception and processing of psi signals.
A key concept in Becker's scheme is his belief in the presence, in humans and other organisms, of a dual system for receiving and processing information arriving from the environment. The system we are all aware of and which scientists study in depth is the nerve impulse system, which transmits digital signals; i.e., 0s and 1s. This system connects to all our everyday senses and controls our motor functions. The second system Becker designates as "primitive." It transmits information in analog (continuously varying) form via electrical currents and magnetic fields, rather than as impulses along neurons. This second system is not recognized by mainstream science.
Becker advances the notions that: (1) Psi-type phenomena are actually handled by the "primitive" analogsystem; (2) The flood of information normally arriving from our sensory organs via the "modern" digital system masks the psi-type signals; and (3) These assertions are consistent with the elusive nature of psi phenomena in both everyday experience and the parapsychological laboratories. Becker's ideas also jibewith experimental evidence that the psi faculty is suppressed by electromagnetic storms, which (presumably) act only upon the "primitive" analog system. Becker readily admits that the physical basis for the generation, transmission, and reception of psi signals is unknown.

Music has done so by making a pact with electricity, electronics and electromagnetic waves. These forces, at once technological and utterly cosmic, have shifted music into more abstract and virtual realms. The growth of the soundscape, from tubular bells to dark ambient drones, has everything to do with electronics and its relationship to the emergence of new virtual spaces. Most "virtual realities" today are constructed primarily with polygons and animation, but in the future we will tune into VR through 3D soundwaves as well. Sonic navigation. Resonance as gateway.
The widespread electrification of music following World War II also came coupled with the rapid spread of rhythmicmemes whose code could be traced back through slave-routes to the motherland. Roots became waves, propagating in echo-pulses through the electronic diaspora. Today, billions of people across the globe explore heightened states of pleasure and consciousness by throwing themselves into intensely rhythmic dance. As the Brazilian ethnomusicologist Hermano Vianna told me: Africa won.
