How Electromagnetic Fields (EMFs) affect us
Electromagnetic Fields (EMFs) around us
What is electromagnetic energy?
Electromagnetic fields (EMFs)
are force fields having both electric and magnetic components, carrying a definite
energy, and capable of producing an action at a distance
Electromagnetic radiation consists of two traveling-companion
waves:
(1)
An electrical field (E-Field).
Created by voltage (a potential difference between two points)
and determines the force with which electricity is pushed through an
electrical pathway (e.g. a wire, nerves, body's meridians) to produce
a current. E-Field strength is measured in volts per meter (V/m).
E.g. A plugged-in, unlit lamp or a charged
battery has an electric field. An electric field varies with the amount of the source
voltage and decreases rapidly with the distance between the two points.
(2) A magnetic field (B-Field).
A flowing electric current always produces an expanding magnetic field
in addition to an electric field, with lines of force at a 90-degree
angle to the direction of current flow.
E.g. A lit lamp or an operating appliance has both an electric and a magnetic
field. B-Field strength is measured in amperes per meter (A/m).
E-Fields and B-Fields travel at right angles to each other and at right
angles to the direction of wave propagation. Together they make up the total EMF.
EMF strength indicates how many volts or amperes the EMF
will induce in a receiving antenna that is one meter long .
Currents changing direction produce EMFs
which change direction
i.e. They vibrate/oscillate.
EM waves arise as a consequence of the following two concurrent
effects:
(1) A changing
electric field. If
a current is fluctuating (vibrating), E.g. alternating Current (AC), the EM waves
will fluctuate along with it. This changing field is characterized by its rate of
fluctuation or vibration, called its frequency. Frequencies are expressed in cycles
per second or Hertz (Hz.)
or (2)
A changing magnetic field. Induces an oscillating
current in an electrical pathway, which in turn creates a changing electric field
(see above).
Natural vs. Manmade
Changing times
Natural EMFs are provided by the Earth, sunlight and
nature. Visible light and random lightning discharges have created geomagnetic
fields and electromagnetic forces that have been constant for millions of years.
Unnatural EMFs were first introduced
when Thomas Edison built the first power station in New York City.
After
100 years of using electromagnetism in technology, we now have an electromagnetic
environment unlike any before. Some experts
believe that the wide spectrum of artificial man-made EMF radiation masks the
natural
beneficial frequencies.
Earth's geomagnetic field strength is slowly declining.
According to Professor
Bannerjee of the University of New Mexico, the field has lost up to half its
intensity in the last 4,000 years.
It
makes sense that the EMFs created by God were meant to be absorbed for the
purpose of promoting health.
In contrast, exposing our body to unnatural EMFs
never meant to be in our environment may have any number of detrimental effects
on our health.
