EMF meters measure AC and DC currents in an area, with sensitivity varying by model. There are analog and digital meters, each with different benefits and features. EMF meters are popular in paranormal investigation and can detect different types of electric fields.
Whether it’s hunting ghosts or checking the electrical currents in a house, an electromagnetic field meter (EMF meter) is the tool of choice. EMF meters measure AC and DC currents, or fields of electricity, within a certain area. Meter sensitivity can vary by model and manufacturer, but most can measure a range of electromagnetic activity between 60 and 50 hertz (Hz). Other EMF detector meters can detect fields as low as 20Hz, although these are expensive and generally only used in scientific research fields.
There are two types of basic EMF meters, analog and digital. An analog EMF meter allows the user to read results as they occur over a field marked by different lines and measurements. A digital EMF meter displays the results on a digital screen. Each has its distinct benefits, with proponents of both types claiming that the EMF meter you choose is more accurate. Within these two types, there are myriad features available to the consumer, including flashing lights to signal a sudden change in EMFs or audio noises such as chirps and beeps to indicate the same.
Outside of scientific research, electrical work, and DIY, EMF meters have grown in popularity in the pseudoscience of paranormal investigation. While widely disputed by many, it is the belief of those within this field that when a ghost or spirit is present, the electromagnetic fields will change in frequency or, more simply, there will be a sudden spike or jolt of energy. This is the apparent reasoning behind the common sensation of hairs standing up on the back of someone’s neck, that a change in the electrical currents of the air reacts with the body’s built-in sensors. With the increase in paranormal use of the EMF meter, consumers are finding that the overall cost of the basic models decreases, due to the rapid increase in popularity.
Detecting electric fields with an EMF meter can also vary depending on the variety used. Some can only analyze the change in EMFs over time, or EMFs generated by man-made sources, or AC currents. Other types can measure wavelengths naturally occurring in the Earth’s magnetic field, also known as DC currents. Some EMF meters can measure both. Some people prefer one or the other, while serious paranormal hobbyists or home improvement enthusiasts find it helpful to have a meter that can read both.
