Know about ELF Waves?

The best way for people to understand electromagnetic waves is to think of the ocean’s waves. Some waves in the ocean are big, and some are small, size is amplitude

Some beaches have waves that come quickly and some have waves that come slowly, this is called the frequency that the waves comes. 

Researcher figured out how they could change the amplitude or the frequency of electromagnetic waves in a controlled way, and this is called amplitude modulation or frequency modulation.

Because all electromagnetic energy beams travel the same speed 3 x 10¹º cm/sec, an energy beam with a short wave must have many more of those short waves pass in a given time such as a day than a long wave. The shorter the wave the greater the frequency that a wave will arrive. While our image of an ocean is that it moves up and down in relation to the surface. 

In other words, the ocean wave moves (vibrates) up and down in relation to the surface (a mathematical plane). Electromagnetic waves vibrate in 3 dimensions (relative to 3 planes), generally they are only drawn as one-dimensional waves. Our brains operate on waves that are very low frequency (from one cycle per second) to about 50 cycles per second. A cycle per second is called a Hertz (Hz). Due to the wide range of different amplitudes and frequencies it has been more practical to induce various measuring units.

Since the late 1970s, questions have been raised whether exposure to ELF electric and magnetic fields (EMF) within this range of frequencies produces adverse health consequences.

External ELF magnetic fields induce electric fields and currents in the body which, at very high field strengths, cause nerve and muscle stimulation and changes in nerve cell excitability in the central nervous system. Health effects related to short-term, high-level exposure have been established and form the basis of two international exposure limit guidelines (ICNIRP, 1998; IEEE, 2002).

ELF at human perceivable kV/m levels is said to create an annoying tingling sensation in the areas of the body in contact with clothing, particularly the arms due to the induction of a surface charge by the ELF. 7% of volunteers described the spark discharges as painful where the subject was well-insulated and touched a grounded object within a 5 kV/m field. 50% of volunteers described a similar spark discharge as painful in a 10 kV/m field

ELF radiation can have adverse effects on the pineal gland as well, depending on the frequency of radiation. According to one source, 60 Hz is most effective at affecting the gland and suppressing melatonin production. This frequency is the frequency of standard US electrical currentScreen shot 2014-03-15 at 6.07.07 AM
