For more than a century, engineers have chased new ways to turn the planet’s natural motions into usable power, from tides to ...

Research groups have made a breakthrough in the field of hard disk drives (HDD) by demonstrating the feasibility of multi-level recording using a three-dimensional magnetic recording medium to store ...

Schematic illustration of altermagnetism in a single-orientation RuO₂ thin film, depicted based on X-ray magnetic linear dichroism and spin orientations. A joint research team from NIMS, The ...

A magnetic cloak works by diverting external magnetic fields so that, to an external observer, the object appears to be absent or invisible. Although this idea ...

A magnetometer is a device that measures magnetism: the direction, strength, or relative change of a magnetic field at a ...

Forbes contributors publish independent expert analyses and insights. An award-winning reporter writing about stargazing and the night sky. Using 11 years of magnetic field measurements from the ...

Magnetic fields play an important—if sometimes underappreciated—part in planetary systems. Without a strong magnetic field, planets can end up as a barren wasteland like Mars, or they could indirectly ...
