Have you ever wondered how a magnetometer works? We sure have, which was why we were happy to stumble upon this article on simple homebrew fluxgate magnetometers. As [Maurycy] explains, clues to how a ...

On 21 June, the Chinese Academy of Sciences hailed a breakthrough – a major upgrade to a kind of quantum device that measures magnetic fields. Magnetometers have been used to detect submarines since ...

A new technique that uses magnetic fields to detect underwater objects has been unveiled by physicists in the UK. The fields induce electric currents in metallic objects and the resulting magnetic ...

A magnetometer is an electronic device capable of measuring magnetic fields or magnetic dipole moment. Magnetometers are widely used for measuring the Earth’s magnetic field, in geophysical surveys, ...
