It is much like the floating globes you can buy, except it works by balancing the forces of permanent magnets with electromagnets, rather then simply using combinations of permanent magnets. Furthermore, we describe mainly the modes of action of low frequency magnetic energy and 3 physical concepts that are seen as the connecting link between electromagnetic fields coupled into connective tissue and biochemical repair and growth processes in bones and cartilage.

Finally all the domains are lined up, and further increases in current only cause slight increases in the magnetic field: this phenomenon is called saturation. When the current in the coil is turned off, in the magnetically soft materials that are nearly always used as cores, most of the domains lose alignment and return to a random state and the field disappears. However some of the alignment persists, because the domains have difficulty turning their direction of magnetization, leaving the core a weak permanent magnet online. Frame 2 shows what we'd see if we were observing all this from a frame of reference moving along with the lone charge. Why don't the charge densities also cancel in this frame? Relativity tells us that moving objects appear contracted to an observer who is not moving along with them ref.: Selected Papers on Electron Optics (S P I E Milestone Series) Radio waves termed microwaves are used for high-speed communications links, heating food, radar, and electromagnetic weapons, that is, devices designed to irritate or injure people or to disable enemy devices. The microwave frequencies used for communications and radar are subdivided still further into frequency bands with special designations, such as "X band" and "Y band."

What makes the various forms of electromagnetic fields so different? One of the main characteristics which defines an electromagnetic field (EMF) is its frequency or its corresponding wavelength. Fields of different frequencies interact with the body in different ways. One can imagine electromagnetic waves as series of very regular waves that travel at an enormous speed, the speed of light , e.g. University Physics: Electricity and Magnetism

James Clerk Maxwell drew attention to the separate physical phenomena in 1861. [21] [22] This is believed to be a unique example in physics of where such a fundamental law is invoked to explain two such different phenomena. [23] Einstein noticed that the two situations both corresponded to a relative movement between a conductor and a magnet, and the outcome was unaffected by which one was moving A Treatise On Electricity And Magnetism: Pt.
