Static vs. Electromagnetic Fields

How do Static Magnetic Fields and Electromagnetic Fields Differ?

A static field does not vary over time. A direct current (DC) is an electric current flowing in one direction only. In any battery-powered appliance the current flows from the battery to the appliance and then back to the battery. It will create a static magnetic field. The earth’s magnetic field is also a static field. So is the magnetic field around a refrigerator magnet, and around a bar magnet that can be visualized by observing the pattern that is formed when iron filings are sprinkled around it.

In contrast, time-varying electromagnetic fields are produced by alternating currents (AC). Alternating currents reverse their direction at regular intervals. In most European countries electricity changes direction with a frequency of 50 cycles per second or 50 Hertz. Equally, the associated electromagnetic field changes its orientation 50 times every second. North American electricity has a frequency of 60 Hertz.

Electromagnetic field therapy devices may use AC current or DC current as the source current from which to derive a time-varying, pulsating electromagnetic field.

Static magnets produce only one field strength and no frequency. Cells habituate to that field strength.

Dr. Walter Glück, a physician in Germany, has eloquently and humorously described the difference between static and dynamic, time varying pulsed electromagnetic signals. He likens the static magnetic signal to someone saying: “I love you, I love you, I love you, I love you” in a repeated, mechanistic, strictly monotone fashion with no voice inflections and no changes. Though “I love you” is a pleasant message, when it is droned over and over (and over!) in unchanging fashion, the recipient gets bored with it, and the message (or “signal”) completely loses its impact. Contrast this to the person who exclaims: “I love you!” in a variety of ways, with enthusiasm, passion, and ever-changing voice inflection. The message never gets old and never loses its power. These ever-changing “I love you” signals are the equivalents of the time varying, pulsating electromagnetic impulses generated by pulsating electromagnetic field therapy devices.

An example of the importance of the difference between static and electromagnetic fields can be illustrated by discussing ion transfer inside the body. Ion transfer inside the body is essentially driven by electrical charges at the cell membrane surface. If membrane electrical charge is adequate, the influence of a static magnetic field will promote the flow of nutrients through the membrane’s transport channels. However, if the cell membrane potential is low, as with illness, static magnets have much less influence.

Static magnets depend on the presence of motion to exert their biological effects. By contrast, time varying, pulsating electromagnetic fields literally supply their own motion, and therefore exert more consistent biological effects.
