Measuring instruments designed to detect and measure the magnetic flux strength (scalar magnetometers) and/or also its direction (vector magnetometers) close to the instrument. These devices typically consist of an electronic unit, magnetic field detectors, and a display that shows the value of the magnetic flux level (typically measured in milliweber or maxwell). Magnetometers are used mainly in healthcare facilities to measure weak magnetic fields around medical devices to determine if the magnetic field may produce any interference with the operation of the medical device; the instruments are also used to evaluate an appropriate location for new equipment that may be affected by magnetic fields (e.g., magnetic resonance imaging scanners).
