The Fluxgate Magnetometer The fluxgate magnetometer has been and is the workhorse of magnetic field strength instruments both on Earth and in space. It is rugged, reliable, physically small, and requires very little power to operate. These characteristics, along with its ability to measure the vector components of magnetic fields over a 0.1 nT to 1 mT range from dc to several kHz, make it a very versatile instrument. Geologists use them for exploration and geophysicists use them to study the geomagnetic field. mine detection, vehicle detection, and target recognition. 芯丽捐柒尝野蚂架抿吸彩浴猾嗜哇订向沁潦守攫约乒耽癣谐仗衬狼筛抄痔PART 2 Magnetic Sensors.PART 2 Magnetic Sensors.
