A U.K.-based company announced last week that they’d successfully developed, in just three months, a magnet that doesn’t use rare earth metals at all using AI—according to the company, that ...
Scientists have finally proved the existence of a new type of magnet, after previously believing it impossible.. The team that discovered the phenomenon, which is called altermagnetism, say it ...
The relatively low rare earth content (12% by volume, 26.7% by mass) and the relative abundance of neodymium and iron compared with samarium and cobalt makes neodymium magnets lower in price than the other major rare-earth magnet family, samarium–cobalt magnets.
More recently, and in part spurred on by the growth in battery electric vehicles, there has been much innovation in permanent magnet motors. These rely on high field permanent magnets relying on rare earth minerals. Hydrogen cryomagnetics provides for the possibility of superconducting induction motors cooled by liquid hydrogen at approximately ...
Ferromagnetism is a property of certain materials (such as iron) that results in a significant, observable magnetic permeability, and in many cases, a significant magnetic coercivity, allowing the material to form a permanent magnet. Ferromagnetic materials are noticeably attracted to a magnet, which is a consequence of their substantial ...
