Investigation of changes in properties of water under the action of magnetic field

Professor Pang Xiao-Feng and Deng Bo studied the properties of water, and their changes under the action of a magnetic field were gathered by the spectrum techniques of infrared, Raman, visible, ultraviolet and X-ray lights, which may give an insight into molecular and atomic structures of water.

First detection of magnetic field in distant galaxy produces surprise

Using a powerful radio telescope to peer into the early universe, a team of California astronomers has obtained the first direct measurement of a nascent galaxy's magnetic field as it appeared 6.5 billion years ago.

Lava flows reveal clues to magnetic field reversals

Ancient lava flows are guiding a better understanding of what generates and controls the Earth's magnetic field – and what may drive it to occasionally reverse direction.

Surprisingly rapid changes in the Earth's core discovered

In a recent paper published in Nature Geoscience, the geophysicist Mioara MANDEA from the GFZ German Research Centre for Geosciences, Potsdam and her Danish colleague Nils OLSEN from the National Space Institute/DTU Copenhagen, have shown that motions in the fluid in the Earth’s core are changing surprisingly fast, and that this, in turn, effects the magnetic field of our Planet.

A supra new kind of froth

To see the latest science of type-I superconductors, look no further than the froth on a morning cup of cappuccino. A team of U.S. Department of Energy's Ames Laboratory physicists and collaborating students have found that the bubble-like arrangement of magnetic domains in superconducting lead exhibits patterns that are very similar to everyday froths like soap foam or frothed milk on a fancy coffee.

Milky Way team works scene of dead star

Like a team of forensic detectives in a television show that could be called "CSI: Milky Way," a University of Chicago astrophysicist and his associates are piecing together how a mysterious infrared ring got left around a dead star that displays a magnetic field trillions of times more intense than Earth's.

New understanding for superconductivity at high temperatures

An international research team has discovered that a magnetic field can interact with the electrons in a superconductor in ways never before observed.

News from Earth's magnetic field

It is widely known that the geomagnetic field shields our planet against highly energetic cosmic particles. The importance of the magnetic field for answering geological, tectonic or even archaeological questions is less known.

Magnetic Snakes Create Water Current

Physicists at Argonne National Laboratory have found that magnetic particles suspended in water and subjected to an alternating magnetic field will form snake-shaped structures that can control the flow of the surrounding fluid.

Researchers improve ability to write, store information on electronic devices

New research led by the U.S. Department of Energy's Argonne National Laboratory physicist Matthias Bode provides a more thorough understanding of new mechanisms, which makes it possible to switch a magnetic nanoparticle without any magnetic field and may enable computers to more accurately write and store information.

Magnetic sensors in birds other than migrating birds

40 years ago, Prof. Dr. Wolfgang Wiltschko was the first to prove that migrating robins use the Earth’s magnetic field to direct themselves during migration. Their magnetic sensor showed them the course of the field lines of the Earth’s magnetic field.
