A solar tsunami observed by NASA’s Solar Dynamics Observatory (SDO) and the Japanese Hinode spacecraft has been used to provide the first accurate estimates of the Sun’s magnetic field. Solar tsunamis ...

High school students in Portugal programmed a small, inexpensive Raspberry Pi computer to measure Earth's magnetic field from the International Space Station. When you purchase through links on our ...

Researchers at the University of Colorado Boulder (CU Boulder) have made a significant advance in magnetic field measurement. They have developed a new technique that uses atoms as highly precise ...

Although the Earth’s magnetic field is reliable enough for navigation and is also essential for blocking harmful solar emissions and for improving radio communications, it’s not a uniform strength ...

Physicists and engineers have developed a groundbreaking method to measure magnetic field orientation using atoms as tiny ...

A team of scientists, led by Boy Lankhaar at Chalmers University of Technology, has solved an important puzzle in astrochemistry: how to measure magnetic fields in space using methanol, the simplest ...

In one of the earliest magnetic measurements, primitive mariners used lodestones—magnetized pieces of magnetite—to determine the earth's magnetic field. Today, thousands of applications require the ...

Berkeley -- Capturing the coldest atoms in the universe within the confines of a laser beam, University of California, Berkeley, physicists have made a device that can map magnetic fields more ...

Now more than ever, permanent magnets and electromagnets play a critical role in today’s advanced applications. From high-performance electric motors to magnetic nano-machines and high-reliability ...

A magnetic flow meter relies on Faraday's Law of Induction to measure the flow of a fluid. Magnets outside the pipe create a magnetic field. Electrodes are located perpendicular to the magnets. A ...

The Earth’s invisible shield is showing signs of strain. A vast weak spot in the planet’s magnetic field, located over the South Atlantic Ocean, has expanded rapidly in the past decade, sparking ...
