High-precision magnetic field sensing

Scientists have developed a highly sensitive sensor to detect tiny changes in strong magnetic fields. The sensor may find widespread use in medicine and other areas.

Earth's magnetic poles not likely to flip

The emergence of a mysterious area in the South Atlantic where the geomagnetic field strength is decreasing rapidly, has led to speculation that Earth is heading towards a magnetic polarity reversal. However, a new study ...

Magnetic bacteria and their unique superpower attract researchers

As a graduate student in the 1970s, microbiologist Richard Blakemore probably wasn't expecting to discover a new bacterial species with a never-before-seen ability. While studying bacteria that live in muddy swamps, he observed ...

Magnetism at nanoscale

As the demand grows for ever smaller, smarter electronics, so does the demand for understanding materials' behavior at ever smaller scales. Physicists at the U.S. Department of Energy's Ames Laboratory are building a unique ...
