2. MEMS magnetic field sensor - Wikipedia

   en.wikipedia.org/wiki/MEMS_magnetic_field_sensor

   A MEMS magnetic field sensor is a small-scale microelectromechanical systems (MEMS) device for detecting and measuring magnetic fields (magnetometer). Many of these operate by detecting effects of the Lorentz force : a change in voltage or resonant frequency may be measured electronically, or a mechanical displacement may be measured optically.

3. Magnetic anomaly detector - Wikipedia

   en.wikipedia.org/wiki/Magnetic_anomaly_detector

   A magnetic anomaly detector (MAD) is an instrument used to detect minute variations in the Earth's magnetic field. [1] The term typically refers to magnetometers used by military forces to detect submarines (a mass of ferromagnetic material creates a detectable disturbance in the magnetic field ).

4. SQUID - Wikipedia

   en.wikipedia.org/wiki/SQUID

   These are turn-key systems, made by several manufacturers, that measure the magnetic properties of a material sample which typically has a temperature between 300 mK and 400 K. [20] With the decreasing size of SQUID sensors since the last decade, such sensor can equip the tip of an AFM probe. Such device allows simultaneous measurement of ...

5. Magnetometer - Wikipedia

   en.wikipedia.org/wiki/Magnetometer

   Helium vector magnetometer (HVM) of the Pioneer 10 and 11 spacecraft. A magnetometer is a device that measures magnetic field or magnetic dipole moment.Different types of magnetometers measure the direction, strength, or relative change of a magnetic field at a particular location.

7. Hall effect sensor - Wikipedia

   en.wikipedia.org/wiki/Hall_effect_sensor

   To solve this problem, Hall sensors are often integrated with magnetic shielding of some kind. Mechanical positions within an electromagnetic system can instead be measured without the Hall effect using optical position encoders (e.g., absolute and incremental encoders) and induced voltage by moving the amount of metalcore inserted into a ...
