The EMF detector is an important tool in many ghost hunters kits. They use it to detect if there are ghosts in the room. Ghosts are said to give off electromagnetic fields (though there is no scientific evidence to it)
What Does it do? How Does it Work?
An EMF meter is an instrument for measuring electromagnetic fields. EMF meters measure A/C currents which are usually man-made. They work very similarly to a radio antenna, but with a very different detection characteristic.
What is it Used for?
In everyday life, an EMF meter is used for diagnosing problems with power lines and electrical wiring.
