Many people are worried that t

electromagnetic

fields encountered in every day life cause cancer, but there is very little
conclusive research in this area.

However, there are studies that show some people are
sensitive to
electromagnetic field
s in various physical ways.


What is an
Electromagnetic Field?


Electromagnetic wavelengths are made up of an electric field produced by an
electrically
charged

stationary source combined with a magnetic current. These waves ca
rry energy
through free space at

the speed of light and have a
wide
r

frequency spectrum

than radio
waves. The strength of the electric and magnetic properties determines how much and
how quickly energy is transferred to other objects. Scientist
s

are currently conducting
studies regarding the potential health affects of EM w
aves at varying frequencies and
intensities.


Device

Categories


Two main
categories

of EMF detector are available from a bevy of manufacturers. The
single axis device
measures one dimension of wavelengths at a time. The position must
be adjusted to take m
easure of all three axes before a complete reading is shown. The tri
-
axis devices are more accurate and do not need moved during use because it measures all
the axes simultaneously. Some of the newer devices have a memory card that stores data
and transfer
s it to a computer for analysis.


Home Use


During the initial worries over cell phone radiation companies began producing EMF
detectors for public use. These devices are intended to monitor levels produced by
microwaves and other devices inside the home a
s well as nearby power lines and radio
towers. Some people use these devices when looking for a new home which prevents
those that are sensitive from inadvertently living in a high level area. These meters are
also used to test used appliances for unaccept
able emissions.


Paranormal


It is believed that ghosts use electromagnetic energy to manifest in physical ways.
Control readings are taken and fluctuations in the reading may indicate the presence of a
ghost. Paranormal investigators use EMF detectors wit
h other equipment in an effort to
verify or disprove hauntings. These devices provide data on electromagnetic fields and
fluctuations in those fields, but there is no accepted proof of supernatural activity and
regardless of the sensitivity of the unit

not

everyone will accept it as proof of a ghost
