But, there may be another way, albeit a rather special case, where a magnet can not only be levitated, but locked in place using a rotating magnetic field. The video shows a demonstration of how ...

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 ...

The colloids are paramagnetic, so they only behave magnetically when they are near a magnet or an external magnetic field. Calculated changes of the magnetic field create areas on the chessboard ...
