magnetdetektor
Magnetdetektor, or magnetic detector, is a device that senses magnetic fields or magnetic materials and converts the magnetic information into an electrical signal. These detectors span a broad range of technologies, from simple contactless sensors to highly sensitive instruments used in scientific research. The common goal is to translate magnetic interactions into a measurable electrical quantity such as voltage, current, resistance, or inductance.
Several core technologies are used in magnetdetektorer. Hall effect sensors measure the transverse voltage generated by
Applications cover geophysics, space exploration, navigation and attitude sensing in aerospace, industrial automation, and non-destructive testing.
History traces magnet detection from early compass-based methods to modern solid-state and superconducting devices. Hall effect
