so....is the electromagnetic radiation coming from your cell phone good for you, or not? I’m confused.
Magnetism and RF radiation are two different things......................
Electromagnetic radiation is usually alternating. Radio frequencies are of this type. EM radiation can also be a pulse. EM radiation, as its name implies, is composed of a varying electric field and a varying magnetic field. They are out of phase with each other. These EM fields are the one some people think are bad for you, depending on the energy absorbed by your body.
Whether cell phone EM radiation is bad, I don’t know. The jury is out on that one, I think.
A magnetic field is just that. With a magnet, the field is constant. With an electromagnet, the magnetic field can be constant if the current in the wires is constant or varying is the current varies. If the current reversed direction, the magnet polarity reverses. I haven’t heard anyone say magnetic fields alone are bad for people, but I may be wrong.
My guess is that the magnetic field in this blood therapy is relatively constant to get the blood cells to get organized in one direction. Flipping the field back and forth would seem to be counterproductive.
