Lecture
Magnetic Sensors: Fluxgate and Reed Relay
Description
This lecture covers the principles and applications of magnetic sensors, focusing on fluxgate and reed relay technologies. It explains the operation of fluxgate sensors for measuring weak magnetic fields and their use in various fields such as MRI, geomagnetism, and earthquake prediction. The lecture also discusses reed relays as on/off sensors or actuators based on magnetic attraction and mechanical rigidity. Additionally, it introduces the concept of DC SQUID as a superconducting quantum interference device for highly sensitive magnetic field measurements.
