The Paranormal - EMF - Electromagnetic Fields
Electromagnetic fields arise from the combination of electric and magnetic fields. Electric fields are produced by charges within an atom while magnetic fields are produced whenever those charges move. So, if an electron within an atom moves, either within itself or to another atom, it produces a magnetic field. Electrons are negatively charged particles. So, they always produce a certain amount of electric fields. The same goes for the positively charged protons. Also, electrons are always spinning on their axes which indicates they are moving and, hence, producing magnetic fields. So, it’s safe to say that if electrons are charged particles and they are always moving that they are always producing electric and magnetic fields. The resultant field produced by such a phenomenon is called the electromagnetic field. It’s the product of the overlapping of electric and magnetic fields.
An electric field that moves, or changes, will generate a magnetic field. A magnetic field that moves, or changes, will generate an electric field. It’s for these reasons why generators can produce electricity and electricity can move electric motors. In a generator, a moving magnet, powered by some other energy source such as gasoline, produces changing magnetic fields that produce electric fields in conductors (wires designed to carry electricity), and, hence, electricity in the form of electrical current (moving charges/electrons). In an electric motor, an electric current produces magnetic fields that force magnetic materials to move (much like a compass moves with the magnetic fields of the earth).
When electrical charges, either positive or negative, change at regular intervals (oscillate), they produce electromagnetic waves: oscillations of overlapping electric and magnetic fields. Electromagnetic waves are the combination of electric and magnetic waves overlapping at right angles to each other, and they travel out into space at the speed of light. Another term used to describe electromagnetic waves is electromagnetic radiation. Light is a form of electromagnetic radiation. Light travels very fast at the rate of 299,792,458 meters per second (in a vacuum). Electromagnetic radiation can travel very long distances. That’s because an electromagnetic wave is self-propagating: the moving magnetic field (in the form of a wave), because of the fact that it’s moving, produces an electric field that also moves with the movement of the magnetic field, and the moving electric field (in the form of a wave), because of the fact that it’s moving, produces a magnetic field that also moves with the movement of the electric field. In other words, since moving magnetic fields generate electric fields and moving electric fields generate magnetic fields, a self-propagating electromagnetic field in the form of a wave is produced. It’s a self-sustaining marriage that makes phenomena like light possible. It’s also what makes TV, radio, microwave ovens, and cell phones possible.
Electromagnetic waves travel at varying frequencies. Frequencies are rates at which waves travel within a certain period of time. For example, the electricity that’s typically used via a monitor screen operates at a frequency of 60 Hertz. One Hertz is the time it takes for once wave cycle to form in one second. The higher the frequency, the more cycles can fit into a period of time. Light, a form of electromagnetic waves, travels at very high frequencies: between 430 trillion and 750 trillion Hertz. Our human eyes can pickup these frequencies as light – it’s what allows us to view the world around us.
EMF METERS
Electromagnetic field detectors are very useful tools provided they are used properly. There are instructions with each type that you should read. These meters detect fluctuations in Electromagnetic fields. EM fields are normally generated by electrical appliances and other items such as computer monitors, cell phones, etc. They are also created by the weather in outer space such as geomagnetic storms and solar flares. When you find an unexplainable field, normally between 2 to 7 milligauss, it is said that is associated with spirit activity. These meters are will not always detect a spirit present, but they are another helpful tool is tracking ghosts. EMF's are measured in units called milligauss. Please note that most of the time we use the meters to rule out certain factors that may cause the misconception of spirit activity. We never solely rely on EMF meters to detect spirit activity but we use them to back up occurrences in conjunction with other pieces of equipment and our personal experiences.
