Eruptions on the sun's surface are probably caused by giant, unstable magnetic plasma arches, a new study reports — a discovery that brings scientists one step closer to predicting solar outbursts ...

With a newly developed neutron tomography technique, researchers have been able to map for the first time magnetic field lines inside materials at the BER II research reactor. Tensorial neutron ...

The primary target of the Magnetospheric MultiScale (MMS) mission is the electron-scale diffusion layer around reconnection sites. Here we study where these regions are found in full three-dimensional ...

(Left) In a magnetic field of moderate magnitude, magnetic flux lines penetrate in the form of defects accompanied by vortices of superconducting currents. (Center) Conceptual diagram of the ...

The famous “superconductor monorail” was a wonderful visual demonstration of what superconductors do to magnets. At first, magnets are repelled by the superconductor. As the temperature drops, a ...

Ever since magnetic monopoles were first predicted by Paul Dirac in 1931, physicists have looked in vain for these elusive entities in everything from particle accelerators to Moon rocks. Now, two ...

It is known that the sun’s corona — the outermost layer of the sun’s atmosphere — is roughly 100 times hotter than its photosphere — the sun’s visible layer. The reason for this mysterious heating of ...

Measuring magnetic fields inside samples has only been possible indirectly up to now. Magnetic orientations can be scanned with light, X-rays, or electrons - but only on the surfaces of materials.
