Latest Magnetic field Stories
By UCLA NewsroomScientists from the California Institute of Technology and UCLA have discovered evidence of "universal ubiquitous magnetic fields" that have permeated deep space between galaxies since the time of the Big Bang.Caltech physicist Shin'ichiro Ando and Alexander Kusenko, a professor of physics and astronomy at UCLA, report the discovery in a paper to be published in an upcoming issue of Astrophysical Journal Letters; the research is currently available online.Ando and...
Super-sized electromagnetic coils are helping explain how aquatic life might be affected by renewable energy devices being considered for placement along America's coastal waters and in the nation's rivers.Scientists with the Department of Energy's Pacific Northwest National Laboratory are examining whether a variety of fish and invertebrates change their behavior during and after exposure to an electromagnetic field similar to those produced by marine and hydrokinetic power devices that...
Just as the path of photons of light can be directed by a mirror, atoms possessing a magnetic moment can be controlled using a magnetic mirror. Research reported in the Journal of Applied Physics investigates the feasibility of using magnetic domain walls to direct and ultimately trap individual atoms in a cloud of ultracold atoms."We are looking for ways to build magnetic systems that can manipulate atoms," says author Thomas Hayward of the University of Sheffield in the United...
For a thrilling eight minutes, NASA researchers will soon get a peek at one of the sun's most mysterious regions, where temperatures fluctuate from tens of thousands of degrees Fahrenheit to several million, and solar flares and coronal mass ejections originate -- potentially threatening spacecraft, Earth-based communications and the lives of explorers in space.To learn more about this turbulent region of the sun, known as the transition region, Marshall solar physicists and engineers have...
Researchers using NASA's fleet of five THEMIS spacecraft have discovered a form of space weather that packs the punch of an earthquake and plays a key role in sparking bright Northern Lights. They call it "the spacequake."A spacequake is a temblor in Earth's magnetic field. It is felt most strongly in Earth orbit, but is not exclusive to space. The effects can reach all the way down to the surface of Earth itself."Magnetic reverberations have been detected at ground stations...
YPRES, Belgium, June 21, 2010 /PRNewswire-FirstCall/ -- Melexis today releases the MLX92211, second generation of Automotive Hall-Effect Latch sensors. The MLX92211 comes as a great successor of the worldwide famous USx88x series by Melexis.

NEW ORLEANS, June 11 /PRNewswire/ -- Robert Hunt, of Linear Power, Ltd., appeared before the Saint Bernard Parish Council in LA during their session on June 1st while the "Top Kill" was still underway where he warned the council that BP's plan to cut the riser pipe would increase the flow of oil two to three fold, which government experts now confirm has happened. Hunt stated that he had pleaded with BP to take immediate action to employ his plan to use strong magnets to stop the leaking...
While attempting to solve one mystery about iron oxide-based nanoparticles, a research team working at the National Institute of Standards and Technology (NIST) stumbled upon another one. But once its implications are understood, their discovery* may give nanotechnologists a new and useful tool.The nanoparticles in question are spheres of magnetite so tiny that a few thousand of them lined up would stretch a hair's width, and they have potential uses both as the basis of better data storage...
Over the last century, astronomers have become very aware of how just dynamic the Sun really is. One of the most dramatic manifestations of this is a coronal mass ejection (CME) where billions of tons of matter is thrown into space. If a CME reaches the Earth it creates inclement "˜space weather' that can disrupt communications, power grids and the delicate systems on orbiting satellites. This potential damage means there is a keen interest in understanding exactly what triggers a CME...
Despite the fact that bats are active after sunset, they rely on the sun as their most trusted source of navigation. Researchers from the Max Planck Institute for Ornithology found that the greater mouse-eared bat orients itself with the help of the earth's magnetic field at night and calibrates this compass to the sun's position at sunset (published online in Proceedings of the National Academy of Science, PNAS, March 29th, 2010)Since the 1940s it has been known that bats use echolocation...
