This book explains the basic principles, available device parameters, and application rules of magnetic sensors and magnetometers.
Chapter 1 presents the basics of magnetism and discusses magnetic quantities and units, magnetic states of matter and magnetic materials for sensor applications. The following seven chapters address the common principles of magnetic sensors.
Chapters 2 to 4 discuss Induction Sensors, Fluxgate Sensors and Magnetoresistors, respectively. Topics covered within these sections include: air coils, search coils with a ferromagnetic core, the theory of fluxgate operation, fluxgate gradiometers, anisotropic magnetoresistance (AMR) and giant magnetoresistance (GMR) sensors, and design examples. Hall-Effect Magnetic Sensors, Magneto-Optical Sensors, Resonance Magnetometers, and Superconducting Quantum Interference Devices (SQUIDS) are discussed in chapters 5 to 8. Amongst the subjects presented are integrated Hall sensors, Faraday and magneto-optical Herr effects, SQUID operation, and applications.
Chapter 9, Other Principles, covers magnetoimpedance and magnetoinductance, magnetoelastic field sensors, and biological sensors. The following chapter discusses the Applications of Magnetic Sensors. This includes biomagnetic measurements, navigation, military and automotive applications, non-destructive testing and space research.
The final two chapters of the book address Testing and Calibration Instruments, and Magnetic Sensors for Nonmagnetic Variables. Topics discussed in these sections include: calibration coils, magnetic shielding, position sensors, torque sensors, and sensors using magnetic liquids.
"Magnetic Sensors and Magnetometers" is suitable for academics and students of physics, geophysics, electrical engineering, and measurement and instrumentation courses; consultants of sensor systems and industrial automation; and users and designers of industrial sensors. This book provides a comprehensive and practical coverage of magnetic sensors and magnetometers.
