EMF
Let’s talk about
this subject called (EM) Electromagnetism.
Electromagnetism is a large,
encompassing theory, so it’s no wonder that many
people do not understand it because we cannot see
it, feel it or even taste it. A basic book on it
will almost immediately dive into the world of
boring mathematics, such as Maxwell’s equations!
Electric and magnetic fields (EMF) are invisible
lines of force that surround any electrical device.
Power lines, electrical wiring, and electrical
equipment all produce EMF. There are many other
sources of EMF as well. The focus of this discussion
is on the basic understanding of EMF--that is, EMF
associated with the generation, transmission, and
use of electric power.
Electric fields are produced by voltage and increase
in strength as the voltage increases. The electric
field strength is measured in units of volts per
meter (V/m). Magnetic fields result from the flow of
current through wires or electrical devices and
increase in strength as the current increases.
Magnetic fields are measured in units of gauss (G)
or tesla (T).
Most electrical equipment has to be turned on, i.e.,
current must be flowing, for a magnetic field to be
produced. Electric fields are often present even
when the equipment is switched off, as long as it
remains connected to the source of electric power.
Brief bursts of EMF (sometimes called "transients")
can also occur when electrical devices are turned on
or off.
Electric fields are shielded or weakened by
materials that conduct electricity--even materials
that conduct poorly, including trees, buildings, and
human skin. Magnetic fields, however, pass through
most materials and are therefore more difficult to
shield. Both electric fields and magnetic fields
decrease rapidly as the distance from the source
increases.
Even though electrical equipment, appliances, and
power lines produce both electric and magnetic
fields, most recent research has focused on
potential health effects of magnetic field exposure.
This is because some epidemiological studies have
reported an increased cancer risk associated with
estimates of magnetic field exposure. No similar
associations have
been reported for electric fields; many of the
studies examining biological effects of electric
fields were essentially negative.
The term "EMF" usually refers to electric and
magnetic fields at extremely low frequencies such as
those associated with the use of electric power. The
term EMF can be used in a much broader sense as
well, encompassing electromagnetic fields with low
or high frequencies.
Measuring EMF: Common Terms Electric fields:
Electric field strength is measured in volts per
meter (V/m) or in kilovolts per meter (kV/m). 1 kV =
1000 V Magnetic fields: Magnetic fields are measured
in units of gauss (G) or tesla (T). Gauss is the
unit most commonly used in the United States. Tesla
is the internationally accepted scientific term. 1 T
= 10,000 G Since most environmental EMF exposures
involve magnetic fields that are only a fraction of
a tesla or
a gauss, these are commonly measured in units of
microtesla (µT) or milligauss (mG). A milligauss is
1/1,000 of a gauss. A microtesla is 1/1,000,000 of a
tesla. 1 G = 1,000 mG; 1 T = 1,000,000 µT To convert
a measurement from microtesla (µT) to milligauss (mG),
multiply by 10. 1 µT = 10 mG; 0.1 µT = 1 mG
The earth produces EMF, mainly in the form of static
fields, similar to the fields generated by DC
electricity. Electric fields are produced by air
turbulence and other atmospheric activity. The
earth's magnetic field of about 500 mG is thought to
be produced by electric currents flowing deep within
the earth's core. Because these fields are static
rather than alternating, they do not induce currents
in stationary objects as do fields associated with
alternating current. Such static fields can induce
currents in moving and rotating objects.
The wavy line at the right illustrates the concept
that the higher the frequency, the more rapidly the
field varies. The fields do not vary at 0 Hz (direct
current) and vary trillions of times per second near
the top of the spectrum. Note that 104 means 10 x 10
x 10 x 10 or 10,000 Hz. 1 kilohertz (kHz) = 1,000
Hz. 1megahertz (MHz) = 1,000,000 Hz.
You cannot see a magnetic field, but this
illustration represents how the strength of the
magnetic field can diminish just 1-2 feet (30-61
centimeters) from the source. This magnetic field is
a 60-Hz power-frequency field.
When it comes to using EMF detectors, may folks have no clue on
how to use them properly or the ability to determine man-made
sources such as (AC), which is alternating current from natural
ones (DC), which is direct current.
The problem is amplified by the fact that most meters are
calibrated at 60Hz AC, the same frequency as household wiring
and other man-made electrical systems. They were not designed
for what we are using them for, such as paranormal research.
Most of us, aka ghost hunters will tell you that ghosts are
believed to emit some kind of
electromagnetic field, so called EMF. However, when asked why
they believe this, many cannot give a good scientific answer
because we are still in the beginning stages of this frontier
research.
Here is some of our hypothesizes explaining how the EMF detector
problem can be solved to some degree in the field of paranormal
research. The scientific method is the best way yet discovered
for winnowing the truth from lies and delusion. The basic
version looks something like this:
1. Observe some aspect of the universe.
2. Invent a theory that is consistent with what you
have observed.
3. Use the theory to make predictions.
4. Test those predictions by experiments or further
observations.
5. Modify the theory in the light of your results.
6. Go back to step 3 and loop again.
So, what is my theory, the basis for ghostly energetic? There is
really only one possibility within
known science, so let’s go to the specialists.
To begin our quest, we must first take a look at the ghost in
the human machine, the conscious of the mind. Professor McFadden
from the School of Biomedical and Life Sciences at the
University of Surrey in the UK believes our conscious mind could
be an electromagnetic field. His theory may solve many
previously intractable problems of consciousness and could have
profound implications for our concepts of mind, spirituality and
even life and death.
There are wide differences in the concepts of consciousness,
which are prevalent among biologists, psychologists, and
sociologists. The threefold meaning of consciousness comes from
the Latin word 'con-scio': a) to cut, b) to make a distinction,
and c) to know.
There are three different ways to know the difference
-- 'con-scientia':
1) Through genetic bio-reactive knowledge,
2) Through personal self-reflexive knowledge, and,
3) Through social, consensually validated knowledge.
Most people consider "mind" to be all the conscious things that
we are aware of. However this is not quite accurate. The
majority of mental activity occurs without awareness. Actions
such as peddling a bicycle or walking can become as automatic as
breathing. The biggest puzzle in neuroscience is how the brain
activity that we're aware of (consciousness) differs from the
brain activity of all of those unconscious actions.
The human brain is a symphony of electromagnetic signals, but
science has had trouble finding the conductor of the symphony.
One of the problems that neurologists have with consciousness is
called the binding problem. The best way to explain the binding
problem is to use the analogy of a tree. A tree seems to contain
thousands of leaves, all of which are contained on several
branches. Neurobiology tells us that the information contained
in the mind (all the leaves) is dissected and scattered among
millions of widely separated neurons. The binding problem is
encountered when science tries to explain where in the brain all
those leaves are stuck together to form the conscious impression
of a whole tree.
How does our brain bind information to generate consciousness?
The data does not seem to add up and our symphony conductor is
once again missing.
Through his research, Professor McFadden realized that every
time a nerve fires, the electrical activity sends a signal to
the brain's electromagnetic field. However, unlike solitary
nerve signals, information that reaches the brain's
electromagnetic field is automatically bound together with all
the other signals in the brain.
The brain's electromagnetic field does the binding that is
characteristic of consciousness. Conscious information
processing is associated with the EM component of ultra low
frequency (ULF) brainwaves in either:
a) Dialectically "denser" parts of the brain in the normal awake
state f consciousness; or
b) a gaseous ionic structure in the vicinity of the mind.
This is why we aka ghost hunters look at EM fields. It is the
basis of life itself (a great book on the
subject that I'd recommend for ghost hunters is " The
electromagnetic origins of life" by Dr. Becker). The brain's EM
field is the only possible thing that could survive bodily
death.
EEG and the brain's state
EEG (Electroencephalography) technology is used to measure
brain's electrical vibrations from the surface of the scalp. The
resulting EEG pattern will contain frequency elements mainly
below 30Hz. The frequencies are categorized into four states as
follows:
State Frequency Range Amplitude State of Mind
Delta 0.5Hz - 4Hz high (up to 200uV) Deep sleep
Theta 4Hz - 8Hz low (5uV - 20uV) Drowsiness (also first stage of
sleep)
Alpha 8Hz - 14Hz high (up to 200uV) Relaxed but alert
Beta 14Hz - 30Hz low (less than 10uV) Highly alert and focused
The dominant frequency in the EEG pattern determines what is
called the current state of the brain. If the amplitude of the
alpha range frequencies is highest, the brain is said to be in
the alpha stage. Note that other frequencies still occur; it is
not meaningful to give any exact frequency your brain is
"operating on."
So what happens at death? Using the first law of thermodynamics
there are several possibilities. First, all that energy could
transform into heat and bleed out of the skull. That would also
mean no afterlife, much less any possibility for ghosts.
Fortunately, there are other possibilities. The EM field could
also change frequency or polarity. Interestingly enough there is
some data out there that suggests that the mind goes into theta
waves just before death, which gives us a possibility of ghosts.
Using what data we have from neurology, we can assume that the
frequency change could not exceed much more than 40Hz or so. The
bottom line is that we are looking for low frequency DC EM
fields. These types of fields are what we need to take a serious
look at. The biggest problem with EMF detectors is that they are
not giving you the most vital piece of information of
the EM field, its FREQUENCY!
They can only give you the power associated with a field. There
is an instrument that can give you both power levels and
frequency. It's a laptop computer. We have a program that
transforms your laptop into a spectrum analyzer. Using the
proper coil or antenna, so can quickly tell if a field is
manmade or not and record the data from the field onto the hard
drive of
the laptop.
