An EMF measuring device.
device taht measures electromagnetic fields
an instrument for measuring the intensity magnetic fields
an instrument that measures the instantaneous value of magnetic induction, B
an instrument which can be used to measure lines of magnetic flux at a specific point on a magnet, but that reading provides no information about the total energy of the magnet being
an instrument which measures the strength of magnetic fields
An instrument used to measure the instantaneous value of magnetic induction, B, usually measured in Gauss (C.G.S.).
A meter to measure Electro-Magnetic Frequency, for this reason often called an EMF Meter. Used to detect psychic hot-spots, as it is alleged that spirits use EMF to manifest or communicate.
An instrument which measures electromagnetic fields. Also call EMF detectors or magnetometers..
