When I was a child with a commonplace book full of ghost research (written in gel pens of course), I asked Santa Claus for an Electromagnetic Field (EMF) detector. I thought I could wave it around my friends’ houses and catch ghosts. I never got one. Bummer.
Flash forward to today: I’m more skeptical than I used to be and I have no idea what EMF means or how it works. So, I did some research for you/us. I am not an expert on the subject or claim to be, so please share any insights or articles in the comments. I’d love to learn more!
The following are notes from my commonplace book.
Definition of EMF: “a physical field produced by electrically charged objects” (Wikipedia).
A more detailed definition of EMF: “Electric and magnetic fields (EMFs) are invisible areas of energy, often referred to as radiation, that are associated with the use of electrical power and various forms of natural and man-made lighting. EMFs are typically characterized by wavelength or frequency into one of two radioactive categories:
- Non-ionizing: low-level radiation which is generally perceived as harmless to humans
- Ionizing: high-level radiation which has the potential for cellular and DNA damage” (National Institute of Environmental Health Sciences)
What causes it? Where can it come from? EMFs can be produced from conventional power sources: computers, power lines, cell phones, home appliances, x-rays. etc (there’s a nifty chart in this article). Also, the further you are from the EMF-producing source, the less harm it does to you.
What effects does it have on humans? Ghosts?
EMFs can affect the brain (and body) in many ways: shred your DNA, alter your morality, train you off food and water, cause seizures, etc (io9).
Research shows compelling evidence that EMFs can induce panic, disorientation, deep fear, and hallucinations–all things associated with hauntings. Though, research cannot 100% prove its validity.
One study published by Michael Persinger (a neuroscientist at Laurentian University in Sudbury, Ontario, Canada) in a 2001 Perceptual And Motor Skills article followed the experience of a 17-year-old girl who claimed to receive visits from The Holy Spirit. She also felt the presence of an invisible baby on her left shoulder. An investigation revealed that the electric clock she slept 10 inches from was producing “electromagnetic pulses with waveforms similar to those found to trigger epileptic seizures in rats and humans” (Marcus, Scientific American). The clock, along with a minor brain injury in her youth, were the cause of her nocturnal visits. The visions stopped when the clock was removed.
For another study, psychologist Christopher French (Goldsmiths, University of London College in London) created a “haunted” room in an apartment building, which was filled with electromagnetic producers and infrasound generators (it is believed that extremely low frequencies can cause strange experiences). French and his colleagues invited 79 people to spend time inside this dimly lit room, warning them that they might experience some strangeness. Participants were also given a psychological evaluation to understand their paranormal beliefs. French said about their findings: “Most people reported at least some slightly odd sensation, such as a presence or feeling dizzy, and some reported terror, which we hadn’t expected” (Scientific American). French and colleagues could not 100% determine that these feelings were attributed to the EMFs.
Some researchers have also theorized why these alleged hallucinations (hauntings) happen most often at night: “Because of the way the solar wind interacts with the Earth’s magnetosphere, the planet’s magnetic field stretches out on the side that’s in darkness. Some researchers hypothesize that this expanded field interacts more strongly with people’s brains” (How Stuff Works).
Some paranormal investigators will say ghosts cause high EMF levels. Another possibility is that high EMF levels create an ideal environment for actual paranormal activity. I once heard that some paranormal investigators will create high levels of EMF so to produce more activity during an investigation.

Thanks! I’ve been wondering what the heck EMFs are supposed to do. It’s an interesting puzzle – are they the source of sensory issues or the gateway? Science!
