Latest Magnetic field Stories

In the nearly five decades since the first lunar surveys were conducted as part of NASA's Apollo program, scientists have advanced a number of increasingly complex theories to explain the vast swaths of highly magnetic material that had been found in the some parts of the Moon's crust. But now a team of researchers from Harvard, MIT and the Institut de Physique du Globe de Paris, have proposed a surprisingly simple explanation for the unusual findings – the magnetic anomalies are...

The ability to detect and respond to magnetic fields is not usually associated with living things. Yet some organisms, including some bacteria and various migratory animals, do respond to magnetic fields. In migratory animals like fish, birds, and turtles, this behavior involves small magnetic particles in the nervous system. However, how these particles form and what they are actually doing is not fully understood. In a new study, published February 28 in the online, open-access journal...

New physical phenomenon could drastically reduce energy consumption by computers Three years ago Professor Christian Pfleiderer and his team from the physics department at the TUM discovered an entirely new magnetic structure in a silicon manganese crystal – a grid of magnetic eddies. Together with the team of Professor Achim Rosch from the University of Cologne, he studied the properties of these eddies, so-called skyrmions, named after the British physicist Tony Skyrme, who predicted...

PROVIDENCE, R.I., Feb. 17, 2012 /PRNewswire/ -- Less than a week after President Obama hosted the White House Science Fair and brought renewed attention to the need for students to pursue careers in science, technology, engineering, and math, Thames & Kosmos announced 18 new additions to its award-winning line of science kits, all of which engage kids with fun hands-on science experiments and activities. The kits were unveiled at the American International Toy Fair, February...

Scientists at the Naval Research Laboratory are part of an international team that has pooled their radio observations into a database, producing the highest precision map to date of the magnetic field within our own Milky Way galaxy. The team, led by the Max Planck Institute for Astrophysics (MPA), used the database they created and were able to apply information theory techniques to produce the map, explains NRL's Dr. Tracy Clarke, a member of the research team. "The key to applying...

[ Watch the Video ] A subset of data that helps map out the sun's magnetic fields was recently released from the Solar Dynamics Observatory (SDO). Observations that measure the strength and direction of magnetic fields on the solar surface -- known as vector magnetograms -- play a crucial role in understanding how those fields change over time and trigger giant eruptions off the surface of the sun such as solar flares and coronal mass ejections (CMEs). Collecting the information needed...
