We spent 44 hours on research, videography, and editing, to review the top choices for this wiki. For those worried about the effects of electromagnetic frequencies being emitted by all the devices in our lives these days, you can now measure them with one of these EMF detectors. These meters are also essential for planning electrical line routes, installing antennae, checking for signal interference, and, even, perhaps, for detecting paranormal occurrences. When users buy our independently chosen editorial picks, we may earn commissions to support our work. Skip to the best emf detector on Amazon.

What Do EMF Detectors Do?

Many things in daily life also create electromagnetic fields.

Once thought to be separate forces, electricity and magnetism have since been joined into a unified theory called electromagnetism. The study of electromagnetism deals with how electrically charged particles interact with each other and with magnetic fields.

Electromagnetic radiation takes many forms. Common examples include radio waves, microwaves, X-rays and gamma rays. Sunlight is also a form of electromagnetic energy, but the visible light it gives off is only a very small portion of the electromagnetic spectrum, which contains a broad range of wavelengths.

Many things in daily life also create electromagnetic fields. Electronics such as cellular phones, video game consoles, computers, radios, and even simple power outlets give off electromagnetic fields. Larger fields are created by larger sources of electricity. Power lines, refrigerators, and generators give off a larger field than a small clock radio, for instance. Electromagnetic fields also exist in nature, such as when the atmosphere becomes charged during a lightning storm.

The job of an EMF detector is to pick up signs of these electromagnetic fields. Stronger currents give off stronger EMF readings. The problem with electromagnetic fields is that they are rarely, if ever, visible to the naked eye, though they are often present in the atmosphere from natural electrical or magnetic sources. This is why EMF detectors are so important.

EMF detectors indicate the presence of electromagnetic frequency through the use of one or more receiving antennae that measure differing AC or DC electrical currents. When EMF is present the meter signals the user. The strength of the reading is a direct indicator of the strength of the frequency.

Why Do Ghosts Give Off EMF Fields?

While EMF meters have been specifically designed for use by utility workers, some researchers have used EMF meters for reasons beyond their original purposes, namely to search for paranormal phenomena.

The paranormal theory of electromagnetism states that a spirit, ghost, or other otherworldly entity either gives off or disrupts the normal electromagnetic fields which can be detected by EMF readers.

Most things in nature, both alive and inanimate, emit at least a weak electromagnetic field. As the law of the conservation of energy is understood to mean energy cannot be created nor destroyed, the electromagnetic nature of the human body is believed to persist after death, should a soul choose not to commit its energy to the afterlife. This energy can then be picked up by EMF readers and used to track, and perhaps communicate with ghosts.

Science contends that the energy borrowed by a human being is given back to the environment which created it after that human's death. This does not need to stop believers in the paranormal from using an EMF reader to track pulses from the beyond. In fact, since the early 21st century nearly half of Americans believe in ghosts, while up to 13 percent have experienced hauntings.

A ghost or paranormal occurrence in electromagnetism is said to give off a milligaus reading in the range of 1.5-6mg, depending on the sensitivity of the meter. Paranormal readings are also never steady readings. Steady readings are nearly always artificially created. Following spikes in an EMF reader is how paranormal hunters are led by ghosts. They may also choose to communicate with the ghosts using the spikes these readers pick up to indicate yes or no answers.

Potential Effects Of EMF Fields On Human Health

Electricity has become an integral part of everyday life, powering things of both convenience and necessity. Where electricity flows, electromagnetic fields exist. Questions about human exposure to electromagnetic fields (EMF) and extremely low frequency (ELF) electromagnetic fields have been addressed by governmental bodies and even the World Health Organization.

Low-frequency magnetic fields cause currents to circulate within the body.

The exposure to electromagnetic fields is anything but new. During the 20th and 21st centuries, however, the exposure to man-made electromagnetic fields has steadily increased. Growing demand for electricity has led to entire populations of cities living within a grid of electromagnetic radiation. In general, the average person is exposed to a large mix of electromagnetic fields every single day. Everything from the generation and transmission of electricity through wall outlets to telecommunications and radio broadcasting creates steady electromagnetic radiation.

Research shows that low-frequency electric fields influence the human body because it is made up of charged particles. When electric fields act on conductive materials like the body, they influence the electric charge at the body's surface. This causes current to flow through the body to the ground.

Low-frequency magnetic fields cause currents to circulate within the body. Depending on the strength of the current, this may influence unnoticed factors like biological processes, or it can influence noticeable factors, such as making the hairs stand on end.

Long term exposure to ELF and EMF fields may negatively impact the immune system as well. They may alter the expression of MCP-1, which helps regulate the body's T cells and natural killer cells. While there have been concerns about EMF exposure for decades, there have been no studies which can confirm these concerns at normal levels. Therefore, exposure to EMF at normal levels is deemed relatively safe to humans.
