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 ...

Supernova debris speeds up neutron stars, strengthening magnetic fields. This explains why low-intensity magnetars still produce bursts.

His design is conceptually similar to an induction cooktop, where alternating magnetic fields create eddy currents that heat metal cookware. But rather than using alternating currents through ...

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.

or “driving,” such as the alternating of positive or negative magnetic field or pulling on a material from one side and then ...

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 ...

This is alternating current or ac ... increasing the rate of rotation increasing the strength of the magnetic field increasing the number of turns on the coil The diagram shows four different ...
