Chinese scientists develop an ultra-sensitive Hall-effect magnetic sensor capable of detecting faint magnetic fields (e.g., a submarine 500m away) from a chip smaller than a grain of dust, overcoming a decades-old sensitivity-noise trade-off.
Ganymede, Jupiter's largest moon, defies typical lunar classifications due to its size (larger than Mercury), intrinsic magnetic field, and a vast hidden saltwater ocean. These planet-like features make it one of the Solar System's most unusual worlds, prompting continued study by missions like NASA's Juno.
An international team of researchers found periodic brightening in the red dwarf star GJ 436, attributing it to interactions between its magnetic field and that of its close-orbiting exoplanet, which has a magnetic field over 10 times stronger than Earth's.
A 2022 study found that the magnetic fields of devices like Apple's AirPods can trigger magnetic modes in implanted cardiovascular devices, potentially preventing them from detecting irregularities. While patients should consult their cardiologists, Apple recommends keeping devices at least 6 inches away from implants.
China's 'Super Microscope' strong light-magnetic field experimental device has completed its six major experimental measurement stations. Expected to be fully operational by the end of 2026, the facility integrates strong laser, strong magnetic field, and ultra-low temperature technologies to study material properties.
Chinese scientists led by Fu Jingcheng achieve stable flight of a helicopter-towed, kite-like array of coils for advanced geophysical surveys, enabling material identification and depth analysis via induced eddy currents.
A global team led by CSIRO has created the largest-ever map of cosmic magnetic fields by measuring light from nearly 4 million galaxies. The "SPICE_RACS" map, made possible by the ASKAP radio telescope in Western Australia, will help scientists investigate fundamental questions about the universe's magnetic origins and evolution.
