摘要: Publisher Summary This chapter discusses the use of ferromagnetic materials; either transition metal or rare earth based. Magnetic sensors and actuators contain magnetic materials as an integral part their functionality, have components specially configured to measure quantities (field, flux density). The simplest form sensor is that a coil wire, with time varying density cutting generating voltage across according Faraday's law electromagnetic induction. introduction material in core can increase sensitivity (sensor application) provide actuation (more force movement available).
