Definition of magnetometer in English English dictionary
an instrument used to measure the intensity and direction of a magnetic field, especially at points on the Earth's surface
intrument for measuring magnetic fields Spacecraft often carry fluxgate magnetometers, which measure components of the magnetic field (3 of them are combined to give its strength and direction) but need to be calibrated Rubidium-vapor and similar instruments measure only the strength, but their reading is absolute, related to atomic constants
an instrument for measuring the direction and/or intensity of magnetic fields Spacecraft often carry fluxgate magnetometers, which measure components of the magnetic field (3 of them are combined to provide all three, giving both strength and direction of the field) but they need to be calibrated Instruments using rubidium vapor measure only the field strength, but their reading is absolute, related to atomic constants
Small cylinders containing sensor coils that operate in a manner similar to inductive loops Developed as alternative to loop detectors for special situations
A device for measuring the magnitude and direction of the Earth's magnetic field
Uses a sealed vessel containing a coiled copper wire surrounded by oil The instrument generates a small current that causes the protons within the oil to spin in the direction of magnetic north The protons then generate a small signal, which is sent to the collection part of the device via the coiled wire By measuring the signal intensity and comparing it to a known atomic constantthe gyromagnetic ration of the protonthe magnetic field intensity at a discrete location can be obtained
An instrument for measuring the intensity of magnetic forces; also, less frequently, an instrument for determining any of the terrestrial magnetic elements, as the dip and declination
an instrument used to measure the intensity and direction of a magnetic field, especially at points on the Earths surface
