Magnetic Fields Can Send Particles To Infinity
2012-04-17 13:34:38

Researchers from the Complutense University of Madrid (UCM, Spain) have mathematically shown that particles charged in a magnetic field can escape into infinity without ever stopping. One of the conditions is that the field is generated by current loops situated on the same plane. At the moment this is a theoretical mathematical study, but two researchers from UCM have recently proved that, in certain conditions, magnetic fields can send particles to infinity, according to the study...

Previous world record shattered during 6-experiment pulse Researchers at Los Alamos National Laboratory's biggest magnet facility today met the grand challenge of producing magnetic fields in excess of 100 tesla while conducting six different experiments. The hundred-tesla level is roughly equivalent to 2 million times Earth's magnetic field. "This is our moon shot, we've worked toward this for a decade and a half," said Chuck Mielke, director of the Pulsed Field Facility at Los Alamos....

Scientists manufacture a cylinder which hides contents and makes them invisible to magnetic fields UAB researchers, in collaboration with an experimental group from the Academy of Sciences of Slovakia, have created a cylinder which hides contents and makes them invisible to magnetic fields. The device was built using superconductor and ferromagnetic materials available on the market. The cylinder is built using high temperature superconductor material, easily refrigerated with liquid...

Moon's Magnetic Anomalies May Be The Result Of Asteroid Collision

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...

Saving Data In Vortex Structures

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...

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 12th-15th in...

Image 1 - Scientists Chart High-Precision Map Of Milky Way's Magnetic Fields
2012-02-04 04:20:03

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...

SDO Helps Measure Magnetic Fields On The Sun's Surface
2012-01-19 13:34:38

[ 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...
