Magnetometre
A magnetometer is an instrument used to measure magnetic fields. These fields can be generated by permanent magnets, electric currents, or by changes in the Earth's magnetic field. Magnetometers are essential tools in various scientific and technological fields.
There are several types of magnetometers, each utilizing different principles to detect and quantify magnetic fields.
Applications of magnetometers are diverse. Geologists use them to map variations in the Earth's magnetic field,
