The struggle for geopolitical supremacy is rapidly becoming a struggle over one critical resource - rare earth magnets. They will determine whether the United States can build military equipment at ...

"Being able to generate magnetism in materials that are not naturally magnetic opens new paths to devices that use abundant and hazardless elements, such as carbon and copper," says postgraduate ...

Researchers have shown that certain metal-organic materials can act as permanent magnets at temperatures of up to 242 °C, while remaining magnetized in external magnetic fields as strong as 7500 ...

Of the 91 metals that we know to exist, only three are truly magnetic at room temperature: iron, cobalt and nickel. This poses something of a problem as we have to rely heavily on these elements for ...

Heusler alloys are magnetic materials made from three different metals that are not magnetic individually. The alloys are used broadly for their magnetic and thermoelectric properties, and their ...

Metals are the only substances that are magnetic. But some metals are magnetic and some are not. The most common magnetic metal is iron. You don't see too many objects made of pure iron but you do see ...

'Soft robots,' medical devices and implants, and next-generation drug delivery methods could soon be guided with magnetism -- thanks to a metal-free magnetic gel developed by researchers. Carbon-based ...

Physicists have devised a method to turn a non-magnetic metal into a magnet using laser light. Physicists from Nanyang Technological University, Singapore (NTU Singapore) and the Niels Bohr Institute ...
