How Does an EMF Detector Work?

Taking an EMF detector with the crew on a ghost-hunting trip has become a very popular thing to do. Every time one a ghost-hunting show comes on, someone inevitably has an EMF detector with them. It has gained popularity in the paranormal and supernatural community for tracking down alleged energy from otherworldly spirits and ghosts.

An electromagnetic field detector, or EMF unit, is used to find beings made up of energy alone, supposedly. It can also be used to locate technology. Finding high EMF reading in a home with loads of electronics is not uncommon. Naturally, these readings can be a bit spooky if the homeowner doesn't know what they are looking at.

The more technology in a home, the higher the EMF reading will be when introduced to these devices. Every day things like blenders, microwaves and hair dryers give off electromagnetic fields. The EMF detector is filled with sensitive pieces and parts that pick out strains of electricity and the fluctuations of magnetic fields. It measures how much of a magnetic field is given off by a particular object.

When the meter is exposed to an electronic device or a spirit the needle will move or jump; it points to how much energy is being put out. In the paranormal world, the EMF detector is said to notice the magnetic field that ghosts or spirits are made up of, thereby detecting a spirit. The higher the reading the stronger the spirit. Suggestively, anything above a two is good.

Now, there is an even greater meter for picking up on supernatural beings and electromagnetic fields. The K-II meter has an LED screen where the predecessor did not. When the meter is introduced to a magnetic field the ultra-sensitive wires that are on the circuit board send a jolt of electrical energy into the amplifier that makes the lights on the meter light up. The lights are an indication of how much energy is in front of the meter. The meter has been used for a few more purposes other than the original, which was designed to indicate high magnetic fields in microwaves and high-tension wires.
