Gaussmeters are a Hall probe, a test current is sent by the meter through the probe. This Hall affect produces a voltage and the meter then records this. Often the highest voltage detected is used or frozen by the meter as voltage fluctuation is common given that magnetic fields are rarely static. Did you know?. Carl Friederich Gauss born in 1777 developed one of the first devices that could measure direction and strength of a magnetic field. He was a pioneer in this type of study and a great mathematician. He created the system used to measure magnetism and is the reason the modern unit of flux density is named Gauss and why we call these units Gauss meters.
