Paranormal Research Tools Not long ago, there were some valid criticisms with the technique of using an EMF detectors with paranormal investigation; especially with ‘ghost hunters’ and ‘paranormal researchers’ using EMF meters for something other than its original, and intended purpose. EMF meters were specifically designed for utility professionals looking for power line and electrical irregularity from the norm. For which they could steadily pickup any anomalies and follow them to their source. Who came up with the idea that ghosts, spirits, entities, may be detected by them is unknown, and the debate continues. Today these tools are not being designed and marketed exclusively to utility workers these days. I have seen more and more EMF readers being designed and marketed to people interested in using them for paranormal- related research. Many models include lights that blink when there is a sudden change in the reading; and some models are being sold with names like "the ghost meter EMF sensor." This suggests a spike in demand for these tools among ghost hunters, and folks with related interest. And what's more, some skeptics have been using electromagnetic energy as a basis for looking at natural causes for paranormal sightings. In other words, even the skeptics are beginning to have similar theories as the believers! As a matter of fact, some skeptics have been wondering as long ago as the 1970s if electromagnetic energy is causing perceptions of ghosts and other paranormal activity. Skeptical researchers, such as Michael Persinger, have done experiments such building a "haunted house" with deliberate areas of strong electromagnetic energy, to see if others would have ghostly experiences. What is EMF Exactly? First of all, let’s clear up a mistake everybody makes in believing that EMF to be ‘Electro-Magnetic Field.’ When in actuality EMF is caused by a physical force from them, or an ‘Electro-Motive Force,’ which is the force that causes electrons to flow through an electrical circuit to produce an electrical current. Because it is not really a force, the term is actually a misnomer; it is more commonly referred to by the initials EMF. EMF is another term for ‘electrical potential,’ or the difference in charge across a battery or voltage source. It’s the potential difference in force of the electrical circuit as the current moves away from its source. Much like water flowing downhill, so is the electrical charge in an electric circuit. The water starting at the top of the hill begins with a certain amount of ‘potential energy,’ just as charges in a circuit start with high electrical potential at its source, or battery. As the water flows downhill, its potential energy drops, as does the ‘electrical potential’ of the electrical charge drops the further it moves through the circuit. At the bottom of the hill, the potential energy of the charge is at a minimum. EMF is what measures this to determine what work must be performed, to bring the charge back to a higher potential after their trip through the circuit. Much like pump would do water, to get it back uphill. EMF Defined Somehow the term EMF meter has become universally accepted to represent ‘Electro Magnetic Force’ by paranormal investigators and has now even been adopted by equipment manufacturers. In this case, we will use BOTH terms to explain what it is, and how it can better be understood, before we review the equipment. So for now, we will continue to use the terms ‘EMF meter’ and ‘EMF force’ to differentiate the difference for EMF readings. The strength of electromagnetic field is affected by the source (current and charge strength) in the environment. In is gauged by its proportional strength from the source. For example, if your magnetic field is generated by a current, then if you double the strength of the current, the strength of your magnetic field will also double, but when measured a distance away, the as the current weakens the magnetic field will as well. The measurement that is normally given as the units to measure electro magnetic field strength is ‘milliGauss (mG)’ or micro Tesla (named after Nicolas Tesla).  The EMF devices used in paranormal research are thus called 'EMF meters,' when in reality they are only Magnetic Field Detectors. Thus it’s worth pointing out that although many EMF meters provide their measurements in milliGauss (mG) the actual unit of measure is called the S.I. Unit (International System of Units), a standard and preferred unit of measurement by scientists. Ghosts, Spirits, Entities and Electromagnetic Fields You asked, "What evidence is available to prove that a ghost causes or even raises an EMF field?"  It has been proven that when a ghost is sighted there is normally a high EMF reading (significant from base/background readings).  Whether the EMF is *caused* by the ghost—or whether something else causes the EMF is a subject of debate. Strong EMF's that move (through walls, through different stories of a building) are certainly NOT normal.  These are unlikely to be caused by man-made power lines, or electrical equipment—which are stationary EMF's.  In my opinion, strong moving electromagnetic fields can be a good indication of paranormal activity.  I have found that moving EMF's will either move away from me, or follow me. In one case, I was able to follow a moving EMF through three floors of a building before it disappeared! Reading a TriField Natural EMF Meter The TriField Natural EM Meter was designed to do field measurements for special research. It detects changes in extremely weak static (DC or "natural" or living) electric and magnetic fields,  and signals with both a tone and the movement of a needle-type gauge if either the electric or magnetic field changes from a previous level. A radio and microwave detector is also included, which reads radio power directly. Because man-made AC electric and magnetic fields are very common and could interfere with readings of static fields, the meter has been designed to ignore AC fields. Normal construction materials don't block magnetic fields, so the meter can be placed indoors and will work equally well, and due to the built-in tone, it can be used in the dark, and will sound the tone at whatever level of field the user sets. Model 1 operates on a standard 9-volt battery, and Model 2 runs on a 9-volt battery or an AC adapter (both included). Model 2 has an input jack for an optional high-sensitivity magnetic coil. Both models are covered by a one-year warranty. The Difference Between AC and DC Magnetic Fields Magnetic The meter on this unit is sensitive to changes of as little as 0.5% of the strength of the Earth's magnetic field, and the tone will sound whether the field increases or decreases. Model 2 is sensitive down to 0.05% of the Earth's magnetic field when the optional external coil is used. After the meter detects an event, when the magnetic field then becomes stable for more than about five seconds, the tone will stop and the needle will return to zero. The meter will remain at rest until the field changes again. The threshold level (squelch level) of the tone is adjustable. The user determines the amount of change in the magnetic field required to sound the tone. If the field changes by the threshold amount, the tone will come on at a low pitch. If the amount of change is larger, the tone's pitch will be higher. This meter can also be used to determine if anything is magnetized. For example, if a bed frame is magnetized, the meter can be held vertically and slowly be swept by hand over the bed. Any changes in the direction or strength of the magnetic field will register. A similar process can reveal the presence of magnetic rocks just below the ground. The TriField Natural EM Meter can detect geomagnetic storms caused by unusual solar activity interacting with the ionosphere (which results in rapid changes of up to 10% in the Earth's magnetic field), as well as the electrical activity of ordinary thunderstorms. It will signal the movement of any distant, strong magnetic sources in the sky, even if the sky is cloudy or the source dips behind a hill. Ball lightning should in theory be associated with a strong magnetic field, and magnetization of metal on the ground has been reported with some sightings of unusual lights in the sky. Electrical When the dial is set to ELECTRIC, the meter is sensitive to electric fields as weak as 3 V/m (volts per meter). Indoors, electric fields typically fluctuate 1 or 2 V/m. By setting the minimum sensitivity to change at 3 V/m, we have designed the meter to disregard this "background noise". A 3V/m field is so feeble that if a 10'x10'x10' room were filled with a field of this strength, it would contain the total amount of energy equivalent to that required to lift a single grain of table salt 1/50th of an inch. Human beings and animals usually emit an electric field which is easily detectable using the TriField Natural EM Meter. In fact, the meter can be used as a motion-activated intruder alarm. It is so sensitive that it can detect the presence of a person through a wall. Though it is not foolproof in this capacity, (sometimes a person will carry no electric charge and thus be "invisible" to the meter), its sensitivity is of interest to researchers in the field of parapsychology. Every type of detectable physical manifestation requires a certain amount of energy. For example, "moving air" requires the expenditure of a small amount of energy to get the air to move initially. Below is a table showing several types of effects or fields emitted by people and objects. It also shows the minimum amount of energy required (per cubic foot of air) to set up that effect or field so that it is stronger than typical indoor "background noise" for that effect or field. Clearly the static electric field is the type that requires the least energy to be detectable. The Electromagnetic Spectrum Radio/Microwave The radio/microwave detector is sensitive from 100,000 to 2.5 billion oscillations per second (100 KHz to 2.5 GHz) and can detect strong or unusual atmospheric electrical activity. It can also detect leaky microwave ovens, cellular or portable phones, walkie-talkies and concealed surveillance bugs. Its minimum and maximum detectable signal strengths are 0.01 milliwatt/cm2 and 1 milliwatt/cm2 respectively. Conclusion The TriField Natural EMF Meters is by far the most preferred unity by paranormal and parapsychology research teams. Because a room can easily be measured that is known to be vacant, and where no electrical energy is present. As well as an early warning system if any unusual atmospheric electromagnetic activity, such as geomagnetic storms or ball lightning is present. In this setting, it does not falsely sound the trigger when people pass near it. It’s Not What You Think!
