This lecture covers the principles of magnetic sensors, including magnetic field, magnetization, permeability, magnetic induction, susceptibility, and different types of materials such as paramagnetic, diamagnetic, and ferromagnetic. It also discusses the applications of magnetic sensors, the measurement of magnetic fields, and the use of anisotropic magnetoresistive sensors. The lecture delves into the sensitivity, linearity, and sign determination of magnetic fields using AMR sensors with 'chevron' geometry, as well as the electronic amplification and configuration of AMR sensors.
