What is EMF?


This article was written by Allen Tiller for the S.A. Paranormal Meet-up in February 2012

What is EMF?

EMF is an abbreviation of “Electromagnetic field”. EMF is a combination of Magnetic and Electrical Fields.  Electrical fields are created by voltage, the greater the voltage the higher field.
Magnetic Fields are created when electric current flows, the greater the current the bigger the magnetic field.
An electric field can exist without current flow, but when the current does flow the magnetic field with vary depending on the amount of power being consumed – the electric field remains constant with no variation
EMF is a constant in nature, it is everywhere around us all the time but remains invisible to the human eye. Electric fields can be made from the building up of electric charges in the atmosphere associated with thunderstorms, Magnetic fields are a constant in nature as well, think about the Earth's poles, created by our magnetic field.

How does this apply to your EMF Meter?

There are many brands and types of meters used to measure EMF, but the two most common categories are single axis and tri-axis meters.
Electromagnetic fields can be generated by AC or DC currents. An EMF meter can measure AC electromagnetic fields, which are usually emitted from man-made sources such as electrical wiring, while gauss meters or magnetometers measure DC fields, which occur naturally in Earth's geomagnetic field and are emitted from other sources where direct current is present...

The majority of EMF meters are calibrated to measure between 50 and 60 hertz.

Meters:


KII Meter


KII (2): is a single axis meter reading between 50Hz and 20,000HZ. Its accuracy and sensitivity are both low, it is useful for measuring power lines, wiring and appliances.

Enzone E.L.F.-Zone




Enzone E.L.F.-Zone: measures between 50 – 10,000 Hertz and is a single axis meter. Its sensitivity and accuracy are considered 'medium'. It is used to locate “hotspots” of EMF and is one of the cheapest units around

 
Electro-Sensor




Electro-Sensor:  Measures between 50-60 HZ is a single axis and is considered a 'medium accuracy and sensitivity' device. It is very cheap.

Gauss Master


Gauss Master: This unit measures between 50 – 60hz and has an audible tone. It is also cheap,. 


Trifield Meter




Trifield Meter: 50-100hz, this meter features 3-axis so is useful for AC magnetic or AC electric fields. It is probably the best of all the EMF meters on the market but does require some research to use it correctly. This meter requires re-calibration.

MEL METER 




Mel Meter: The Mel Meter was designed by Gary Galka after the death of his oldest daughter.  He designed the Meter as a way to communicate with her after she (allegedly) began to visit his family from the spirit realm. The meter is named after his daughter Melissa, it takes its numbers 8704 from her birth and death year, birth being 1987 and death 2004.
The Mel is designed to register AC and DC fluctuations, and temperature changes simultaneously.  The Mel can measure as low as 30Hz (20Hz lower then the K2)
The Mel meter is a “two-axis” meter – it has two independent coils used to measure Emf, the first coil is calibrated to measure 30Hz to 300Hz which falls into the ELF(Extremely low frequency) Range. The other coil measure 20Hz and up
The temperature part of the Mel, the “thermo coupler” can only measure ambient temperatures which make contact with the beaded tip of the probe itself.


Using your Mel Meter (and most other meters) 

Like most EMF meters the Mel Meter coils are very sensitive. It is important not to move the Meter with any kind of jolting action as you will get a false reading. It is best to remain steady if moving the meter, or better yet, use its rear stand, or a small camera stand, to set it somewhere and communicate or take readings.
The EMF sensor of the Mel is located in the top of the unit between the thermo-coupler and the LED glow lamp. 
To measure EMF turn the unit on and select the range in which you wish to measure; Ut – for micro Teslas or Mg for miligauss readings 

Move the unit very slowly, move towards whatever you wish to measure until touching it, the display will give you a reading. Turn the meter at a different angle to the object and observe how your reading is affected – record your highest and lowest readings 

During Investigations: 

I recommend a full sweep of the premises, to begin with, recording on a map all “hotspots” - then, if possible, another sweep with the power turned off. This will give you all-natural EMF readings within the premises. 

What this does is allow you to create a baseline of readings you can then compare to whilst investigating, it gives you the ability to rule out any electrical and natural EMF and therefore raises the possibility of “paranormal” measurements in areas away from high EMF sources
