An extremely slow pulsar has made scientists “slow down” their assumptions about other pulsars. The pace could be caused by a flashing magnetic field rather than pulsar rotation alone. Pulsars and ...

In response to a rotating magnetic field, the dipole moves like a compass needle, aligning all the beads along the same orientation. However, due to magnetic relaxation, the needle does not turn a ...

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 ...
