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 ...

The robots clustered together when they were subjected to a rotating magnetic field. The number of robots that self-organized into flat clusters could be changed, allowing the researchers to ...

This causes the nuclei to produce a rotating magnetic field detectable by the scanner—and this information is recorded to construct an image of the scanned area of the body.
