: Magnetometers detect ferrous metals that could be attracted by a magnet. Steel, iron and iron rich rocks. A good way to remember this is that ferrous metals (detectable) rust or stain yellow/orange. Magnetometers will not detect or see nonferrous metals. Gold, silver, lead, copper, aluminum, and some stainless steel. (This makes the underwater mag indispensable for weapon searches). Aluminum cans and pull tabs are not detected.
Types Edit. Magnetometers can be divided into two basic types: 1  Scalar magnetometers measure the total strength of the magnetic field to which they are subjected, and. 2  Vector magnetometers have the capability to measure the component of the magnetic field in a particular direction.ne type of magnetometer is the proton precession magnetometer, also known as the proton magnetometer, which measures the resonance frequency of protons (hydrogen nuclei) in the magnetic field to be measured, due to Nuclear Magnetic Resonance (NMR).
