We’re used to Hall effect devices as proximity sensors in mechanical systems, used to provide detection of something that has a magnet attached to it. However it’s easy to forget that the devices that ...

Arduino enthusiasts and makers looking for a project to keep them busy this weekend may be interested in a new Arduino powered DIY Gauss meter that once constructed can easily provide feedback on a ...

A series of magnetic-field indicators detects attempts to affect measuring devices, such as utility meters, with magnetic fields coming from permanent magnets. The indicators can be used with water ...

These days when electronic circuits can be found almost anywhere, there is, some people fear*, a different kind of environmental pollution. They call it electrosmog (the word does not appear in any ...

The concept of magnetic field lines and magnetic fields was first studied and observed by Michael Faraday and by James Clerk Maxwell, who made great discoveries in the field of electromagnetism.
