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 reversal could actually have a beneficial effect on Earth. The sun is on the verge of a significant event: a magnetic field reversal. The sun undergoes such a reversal every 11 years ...

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 ...

That could mean the neutron star itself is still rotating hundreds of times a second, but its overall magnetic field—similar to the one that encircles the Earth—is just much slower in behavior.
