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 ...

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 ...

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 ...

The rotating magnetic field lines in the animation represent the invisible influence of the magnetic field on the antihydrogen. The magnetic field does not rotate in the actual experiment.

The inner core of Earth may have changed shape in the past 20 years, according to a group of scientists. The inner core is ...
