2. Magnetoreception - Wikipedia

   en.wikipedia.org/wiki/Magnetoreception

   Although differences in light density seem to drive this behaviour, magnetic alignment appears to play a part. For instance, the natural directional preferences held by these hatchlings (which lead them from beaches to the sea) reverse upon experimental inversion of the magnetic poles.

3. RVmagnetics - Wikipedia

   en.wikipedia.org/wiki/RVmagnetics

   RVmagnetics, a. s. is a research and development company based in Slovakia that specializes in manufacturing and customisation of contactless MicroWire based sensor technology for the industry 4.0, medical and biomedical technologies, electric motors, composites, construction and civil engineering, transportation and logistics.

4. Magneto-optic Kerr effect - Wikipedia

   en.wikipedia.org/wiki/Magneto-optic_Kerr_effect

   The magneto-optic Kerr effect manifests when light is reflected from a magnetized surface and may change both polarization and reflected intensity. The magneto-optic Kerr effect is similar to the Faraday effect, which describes changes to light transmission through a magnetic material. In contrast, the magneto-optic Kerr effect describes ...

5. 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 ).

6. Faraday effect - Wikipedia

   en.wikipedia.org/wiki/Faraday_effect

   Michael Faraday holding a piece of glass of the type he used to demonstrate the effect of magnetism on polarization of light, c. 1857.. By 1845, it was known through the work of Augustin-Jean Fresnel, Étienne-Louis Malus, and others that different materials are able to modify the direction of polarization of light when appropriately oriented, [4] making polarized light a very powerful tool to ...

7. Magnetometer - Wikipedia

   en.wikipedia.org/wiki/Magnetometer

   Magnetometers can be used as metal detectors: they can detect only magnetic metals, but can detect such metals at a much greater distance than conventional metal detectors, which rely on conductivity. Magnetometers are capable of detecting large objects, such as cars, at over 10 metres (33 ft), while a conventional metal detector's range is ...

8. Hall effect sensor - Wikipedia

   en.wikipedia.org/wiki/Hall_effect_sensor

   In such a case the Hall sensor is mounted in a gap in the magnetic core around the current conductor. [24] As a result, the DC magnetic flux can be measured, and the DC in the conductor can be calculated. Hall effect current sensor with internal integrated circuit amplifier. 8 mm opening.

9. Magnetic chip detector - Wikipedia

   en.wikipedia.org/wiki/Magnetic_chip_detector

   A magnetic chip detector is an electronic instrument that attracts ferromagnetic particles (mostly iron chips). It is mainly used in aircraft engine oil and helicopter gearbox chip detection systems. Chip detectors can provide an early warning of an impending engine failure and thus greatly reduce the cost of an engine overhaul.
