Fluxgates

Part of speech: noun

Definitions

1. Devices that measure magnetic fields by detecting the direction and strength using magnetic cores and coils ; instruments used to sense magnetic flux variations for navigation or geophysical surveys ; sensors designed to convert magnetic field changes into electrical signals using principles of electromagnetic induction
2. Components that operate by monitoring shifts in magnetic field direction and intensity via a core and winding system ; apparatus employed to detect magnetic flux changes to aid in orientation or scientific measurement ; tools that transform alterations in magnetic environments into readable electronic outputs
3. Magnetic sensors that utilize a ferromagnetic core and coils to identify the vector and magnitude of magnetic fields ; equipment used for detecting magnetic flux for guidance or study of Earth's magnetism ; devices that translate magnetic field fluctuations into electrical responses for interpretation and use

Etymology: "Fluxgates" is the plural of "fluxgate", a compound formed from "flux" and "gate". The first element comes from Latin "fluxus", "a flowing", the source of the English word for a continuous flow or change. The second is the everyday English "gate", a barrier that opens and closes, here used in the sense of a device that lets a magnetic flux pass through or be controlled. The name describes how the instrument works: it passes magnetic flux through a core and watches how that flow changes, much as a gate regulates what moves through it. Because the two parts are plain English words, the term needs no special history beyond its literal combination, and it reads as a straightforward technical coinage rather than a classical borrowing.

Synonyms: magnetometers, sensors
