A bar magnet creates chaos in plasma

Placing a magnet on your refrigerator might hold up your calendar, but researchers from India's Saha Institute of Nuclear Physics found that placing one outside a plasma chamber causes a localized, fireball-like structure. ...

Boosting the ability to detect superweak magnetic fields

Each beat of your heart or burst of brain activity relies on tiny electrophysiological currents that generate minuscule ripples in the surrounding magnetic field. These field variations provide the basis for a range of research ...

Lunar sonic booms

The sonic boom created by an airplane comes from the craft's large, speeding body crashing into molecules in the air. But if you shrank the plane to the size of a molecule, would it still generate a shock wave?

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.

National MagLab racks up new world record with hybrid magnet

After a decade of planning, designing and building, the Florida State University-based National High Magnetic Field Laboratory now has the strongest magnet in the world for nuclear magnetic resonance (NMR) spectroscopy, a ...
