Abstract

Magnetic field strength is measured using a variety of different technologies. Each technique has unique properties that make it more suitable for particular applications. These applications can range from simply sensing the presence or change in the field to the precise measurements of a magnetic field’s scalar and vector properties. A very good and exhaustive fundamental description of both mechanical and electrical means for sensing magnetic fields can be found in Lion [1]; less detailed but more up-to-date surveys of magnetic sensor technologies can be found in [2,3]. It is not possible to adequately describe all of these technologies in the space available in a handbook. This chapter concentrates on sensors that are commonly used in magnetic field measuring instruments.
