A magnetic microrobot navigates lung airways, drills microlesions, gathers biomarkers, and rapidly classifies cancer tissue ...

The Earth’s magnetic field is 0.5 gauss, while the new Chinese magnet reached 351,000 gauss, zooming past the previous world record of 323,500 gauss. . “This validated the reliability of the technical ...

The DC series motor has some desirable properties, but it can become quite dangerous to use if proper safety precautions are ...

Kinetic energy has to do with the motion of an object—the faster it’s moving, the more kinetic energy it has. If you take a ...

The Event Horizon Telescope (EHT) captured the first image of a black hole, which is the supermassive black hole M87* located at the center of the giant elliptical galaxy M87. Subsequent observations ...

After 10 unforgettable years, Magnetic Fields bids a tender farewell to Alsisar Mahal and the village of Alsisar, carrying with us a deep and enduring gratitude for the warmth, generosity, and spirit ...

An instantaneous stop would subject everything not anchored to the planet to a sudden deceleration. At the equator, this means an abrupt halt from a speed of about 1,600 km/h.

Contact systems physically make contact with the debris, such as by a net or a grappling hook, and slow the debris to a point where it can deorbit safely. This method faces the challenge that most ...

Discovered in 1982, PSR B1937+21 is one of the first millisecond pulsars, with an ultra-short period of 1.558 milliseconds and a magnetic field strength only one ten-thousandth that of ordinary ...

Abstract: Active magnetic bearings (AMBs) are developed aiming at higher speed and lower vibration, which imposes improvement of rotor dynamic balancing. Field dynamic balancing based on system ...

Magnetic field data collected by ESA's Swarm satellites and other sources has been coverted into these frightening sounds. The "audio represents the magnetic field generated by Earth's core and a ...
