磁传感器可以根据它们是测量总磁场还是磁场的矢量分量来分类。用于生产这两种类型的磁传感器的技术涵盖了物理学和电子学的许多方面。在这里，我们描述并比较了用于磁场传感的大多数常见技术。这些包括搜索线圈，磁通门，光泵，核旋进，SQUID，霍尔效应，各向异性磁阻，巨磁阻，磁隧道结，巨磁阻抗，磁致伸缩/压电复合材料，磁二极管，磁晶体管，光纤，磁光和微机电系统为基础的磁传感器。还介绍了这些传感器在与地球磁场或围绕地球磁场工作方面的用途。
Magnetic sensors can be classified according to whether they measure the total magnetic field or the vector components of the magnetic field. The techniques used to produce both types of magnetic sensors encompass many aspects of physics and electronics. Here, we describe and compare most of the common technologies used for magnetic field sensing. These include search coil, fluxgate, optically pumped, nuclear precession, SQUID, Hall-effect, anisotropic magnetoresistance, giant magnetoresistance, magnetic tunnel junctions, giant magnetoimpedance, magnetostrictive/piezoelectric composites, magnetodiode, magnetotransistor, fiber optic, magnetooptic, and microelectromechanical systems-based magnetic sensors. The usage of these sensors in relation to working with or around Earth's magnetic field is also presented.
