Now researchers at Nanyang Technological University (NTU) in Singapore have found a way to heat up resins using an alternating magnetic field (PDF), so-called magnetocuring.

These nanoparticles generated heat when exposed to alternating magnetic fields. Interestingly, this heat quickly thawed ...

Many materials store information about what has happened to them in a sort of material memory, like wrinkles on a once ...

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.

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 ...

In 1963, Fred Vine, Drummond Matthews, and others found that the crust surrounding the midocean ridges showed alternating bands ... reversal of Earth's magnetic fields some 900,000 years ...

These magnetic fields can be investigated by looking at ... electromagnetic induction to change the potential difference of alternating currents. Potential difference and current changes can ...
