Researchers are now advocating using electric fields to do this switching. For this, electric fields have an advantage, since they're more amenable to controlling magnetic devices than are ...

Chiu and the team have now mathematically shown that introducing a spatially alternating magnetic field gives rise to additional magic angles and flat bands that are quadruply (four-fold ...

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 ...

Discover the newly developed cobalt-doped iron oxide nanoparticles, improving magnetic hyperthermia treatment for ovarian ...

Made of iron oxide and doped with cobalt, the nanoparticles show exceptional heating efficiency when exposed to an alternating magnetic field. Doping refers to adding something as a means of tailoring ...

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 ...

Targeting magnetic nanoparticles to tumours then applying an alternating magnetic field can improve the contrast for infrared thermal imaging. Like inflamed tissues, malignant tumours have higher ...

a cancer treatment modality that utilizes the heat generated by magnetic nanoparticles under an alternating magnetic field, has shown promise in selectively destroying cancer cells. Nanomagnetic ...
