Berkeley Labs initially produces fully magnetic fluids

As you would expect from a magnetic fluid, the material retains its magnetic properties in virtually any shape. The researchers showed that they can divide droplets into smaller ones or turn them into bullets, cylinders, pancakes, tubes and even into an octopus form while still being magnetic. In addition, the droplets can be adjusted so that their magnetism can be …

This new liquid is magnetic and fascinating

Lodestone, a naturally occurring iron oxide, was the first permanent magnetic material known to man. The Han Chinese used it for divination of boards 2200 years ago; The ancient Greeks wondered why iron was attracted to it. and Arab merchants put it in water bowls to observe the magnet point on the way to Mecca. Today, scientists have used magnets …

Scientists deepen the understanding of magnetic fields surrounding the Earth and other planets

The PPPL physicist Eun-Hwa Kim. Photo credits: Elle Starkman / PPPL Office of Communications Huge rings of electrically charged particles orbit the Earth and other planets. Now, a team of scientists has completed the exploration of waves that move through this magnetic, electrically charged environment known as the magnetosphere, deepen the understanding of the region and its interaction with our …

Magnetic materials help to explain how arctic ice melts

Kenneth Golden, a mathematician at the University of Utah, was reading pictures of Arctic sea ice when he noticed a pattern that seemed familiar to him. Seen from above, the melting sea-ice looked like a white-speckled field with dark spots in which the ice had turned into liquid. For Golden, it seemed terribly similar to the arrangement of the atoms …

Northern lights' social networking reveals true scale of magnetic storms

Credit: CC0 Public Domain              Magnetic disturbances caused by phenomena like the northern lights can be tracked by a 'social network' of ground-based instruments, according to a new study from the University of Warwick.                                                 The researchers, led by Professor Sandra Chapman from the University's Department of Physics, have described the observations of over 100 ground based magnetometers in terms …

Approach to the magnetic singularity

A domain wall (gray field in the middle) separates regions with different spin orientations (green and blue arrows). MIT researchers discovered that a magnetic field applied at a certain angle by a single crystal of a new magnetic quantum material makes it more difficult for electrons to traverse this domain wall. Picture credits: Leon Balents In many materials, the electrical …

In a first, magnetic fields have been spotted between two galaxy clusters

For the first time astronomers have sighted magnetic fields between two galaxy clusters – The fields run between the galaxy clusters Abell 0399 and Abell 0401, which are beginning to merge about 1 billion light years from Earth, researchers report in the June 7 Science . Radiation from electrons zipping through the magnetic fields revealed this magnetism in the gaseous …

Astronomers discover a mysterious, 10 million-light-long magnetic field connecting two galaxy clusters

Close-up of the filament. Image: DSS and Pan-STARRS1 (optical), XMM-Newton (X-rays) PLANCK satellite (y-parameters), F. Govoni, M. Murgia, INAF Scientists have discovered radio waves emerging from space between a pair of galaxy clusters – evidence of intergalactic magnetic fields and fast moving particles in the space between these huge galactic arrays. The universe consists of a vast network of galaxy …
