gaussmeter
Definition
Noun: A gaussmeter is a scientific instrument used to measure the strength and, in some models, the direction of a magnetic field. Its name derives from the unit of magnetic flux density, the gauss.
Usage
A gaussmeter is used to take quantitative measurements of magnetic fields. It is a specific type of magnetometer. * The engineer used a gaussmeter to check for stray magnetic fields around the electrical equipment. * Before setting up the sensitive experiment, they scanned the room with a gaussmeter.
Advanced Usage
- Calibration and Use: High-precision gaussmeters require regular calibration against known standards to ensure accurate readings. They often have a probe or sensor that is placed in the area to be measured.
- Applications: Common applications include quality control in manufacturing (e.g., checking magnets), assessing electromagnetic interference (EMI), geological surveying, and ensuring safety in environments with strong magnetic fields (e.g., near MRI machines).
Variants and Related Words
- Magnetometer (n): A more general term for any instrument that measures magnetic fields. A gaussmeter is a type of magnetometer calibrated in gauss or tesla units.
- Teslameter (n): A meter that measures magnetic flux density in the SI unit, the (1 tesla = 10,000 gauss). Functionally similar to a gaussmeter but using a different unit system.
Synonyms
- Magnetometer
- Fluxmeter (in some specific contexts)
Noun
-
