MAGNETIC FIELDS BASICS
Geomagnetic Fields
 |
The body does not exist outside a magnetic
environment. It never developed from the embryo stage outside
that environment. Some of us may leave it temporarily - astronauts - but you and me won't. ALL biology on the planet
Earth is COMPLETELY dependant on the Earth's magnetic. The Earth
is our natal mother in more ways than we knew. We'll discover
even more ways that is true in time. We are forever dependant on
out Magnetic Mother.

How are we
dependant?
Our cells from the very
beginning of life – intrauterine and
planetary – grew from the beginning in a
complex planetary magnetic field system. We
can’t leave home without it.
The Earth’s MFs comprise:
·
Earth’s overall
DC field – magnetic north and south poles.
·
Rocks under our
feet – as you walk about, there are
continuing changes in field strength under
you feet, entering the body.
·
Schumann
resonances – caused by lightning storms and
much more complex than a single resonance of
8.3 Hz.
·
Geomagnetic
storms/solar flares/coronal discharges
coming in through the polar regions into the
planetary ecosphere.
·
Fields created
by the rotation of the planet and variations
in the ground level fields caused by
tectonic plate movements and the magma in
the Earth’s core– animals sense changes in
these just before an earthquake.
·
Cosmic
radiation moving into and through the
planet’s environment.
·
In recent
history, the man-made EMFs surrounding us
daily, especially in our cities.
Currents are induced in a
human body in motion due to the nonconstant
magnetic field of the Earth. Up to 4
microamperes per square meter occur with
exercises such as bending or rotation of the
arm and up to 15 microamperes per square
meter when travelling at 100 km/hr. These
induced currents change at a rate between 0
Hz and 10 Hz.
Space program managers and
astronauts now understand that being out in
space causes more issues than just the loss
in gravity. Research suppressing the earth’s
magnetic fields is showing that big changes
happen without the background field we have
developed in. An accidental event in a cage
with mice may indicate what can happen to
biology if there should ever be a pole
reversal! It’s not pleasant … but not
irreversible either. There have been
reversals in the Earth’s past. Examination
of the polarization of rocks and sediments
in the Earth’s sea floor has shown these
events.
(Seafloor
magnetic reversal patterns)
Based on measurements of the
Earth's magnetic field taken since about
1850 some paleomagnetists estimate that the
field will decay in about 1,300 years.
However, the field is actually higher than
it has been for most of the last 50,000
years and the current decline could reverse
at any time. Even if Earth's magnetic field
is beginning a reversal, it would still take
several thousand years to complete a
reversal. They are inevitable in the
geologic future too. When the next one will
happen is unknown. Nevertheless, when it
happens the effects on humanity and biology
will be significant although probably
temporary as our physiology adjusts.

Earth's Basic DC field
The
Earth's basic magnetic field is oriented longitudinally, north
to south, as would be expected of any bar magnet.
In this next graphic (below), the dark blue
areas are the areas of the Earth where the magnetic field is the
weakest - generally the equatorial region. As would be expected
the fields are the strongest in the orange and red areas, that
is the polar regions.
How the Earth's magnetic field is produced, is
still subject to speculation.
This is discussed more fully here:
www.phy6.org
This is a good site to find a lot of useful
information on the Earth's magnetic field.
www.ngdc.noaa.gov
Other than a basic fundamental dependence on
the surrounding constant field for basic cellular survival
long-term, the only other major function of this natural totally
enveloping field is for navigation. Animals and humans use this
field and it's "field lines" for navigation and
spatial orientation. The primary senses are most dominant but
humans have a magnetic sense as well, which has been found to
affect dowsing abilities and directional orientation in the
dark. Humans and animals have been found to have natural
magnetite (iron crystals) in our brains and other tissues that
sense magnetic field changes.
The Earth's "static" or DC
background field is important in considering magnetic therapy
with static magnets. Since the overall background field averages
0.5 G, and penetrates completely throughout our bodies, any
magnet with a field strength below this will not be expected to
be active. Because the magnetic field strength of a magnet
decreases with distance from its surface and, once the field
drops to or below the ambient background field strength, it will
be no more effective than the background field in the tissues
from that point out.
Schumann Resonances
These
two websites give scientifically grounded basic descriptions of
the Schumann Resonances:
www.oulu.fi
www.nasa.gov
In fact, the Earth's ionosphere is a very
complex electrical system. See:
www.oulu.fi
The polar aurora is active all the time and is
regularly measured by Earth-bound magnetometers. This site gives
actual measurements from Canada.
www.dan.sp-agency.ca
It is impossible to know exactly how much
ionospheric currents contribute to human exposure versus ground
magnetic fields, since they are a superposition of contributions
from the horizontal ionospheric currents, field-aligned
currents, distant currents in the magnetosphere outside the
ionosphere and currents induced in the Earth's surface.
Because it is very difficult to isolate humans
from all the other fields they interact with on the planet, it
is not clear what impact the Schumann fields themselves have on
humans. It is worth noting that the Schumann frequencies
resonate on the same frequency bands that the human brain does.
At the least then, they can resonate with (scientifically known
as "coupling") the body's energies and strongly affect
brain wave function. Most of us have experienced heightened
sensitivity during lightning storms and even had other
physiologic reactions, including aches and pains.
Rocks
Naturally magnetized rocks in the ground may
also produce some added stimulation to our bodies as we come
into their fields. Smaller ones are called lodestones. Motion
through these fields will add some component of
"time-varied field" stimulation to the body. This site
has additional information on the subject.
www.phy6.org
Solar
Besides the geomagnetic fields discussed
above, electrical solar energy is continually bombarding us as
time-varied fields. These sites have much more information.

Environmental
In
addition to all the above DC and time-varied influence on us,
the Earth is now also bathed in artificial fields created by
man, especially in the past 50 years. These include televisions,
electric trains, microwave ovens, electrical appliances, wiring
of our homes, wireless equipment, radio and television waves,
radar, submarine communications networks, computers, medical
equipment, our cars and cell phones. Even the radial tires from
our cars produce TMFs.
Besides these sources there also occupational
exposures, which can be magnitudes higher than the background
ones. The health consequences of these more extreme sources are
getting increasing study.
As you can imagine our cities have the most EMFs. The Europeans
are calling all this EMF activity "electro-smog."
There are very few "natural" EMF-free areas in the
USA. One such place in the northeast US is the Shenandoah Valley
area. This is a relatively EMF free area because the radio
telescopes there need to be able to "see" into space
without nearby background EMF interference.
There is increasing interest in finding ways
of shielding us individually from this exploding level of
"electro-smog."
