The structure of a sunspot is determined by the local interaction between magnetic fields and convection near the Sun's surface1,2. The dark central umbra is surrounded by a filamentary penumbra ...

Figure 1 Schematic diagrams of two superconducting flux qubit circuits. The conventional qubit (a) requires an external magnetic field to operate optimally, while the new flux qubit (b), using a ...

Magnetic field lines from a bar magnet. (Image credit: snapgalleria Shutterstock ) Earth's magnetic field produces a tremendous amount of magnetic flux, but it is dispersed over a huge volume of ...

Sunspots are temporarily darker areas due to reduced surface temperature, caused by magnetic field flux. "This was a very exciting, but also extremely challenging project.

Four hundred times more powerful than an MRI, the magnetic field was created with a method known as electromagnetic flux compression. The field measured out to 1,200 teslas, a unit of magnetic ...

The poles of the sun’s magnetic field are fading away. But don’t panic: it’s all part of our host star’s usual 11-year cycle of activity.. Over the past couple of years, solar activity ...

Zirconforms above subduction slabs. Rob Lavinsky, CC BY. When we subjected the subduction flux, magnetic reversal rate data and zircon age frequency to statistical analysis, we found a significant ...

Jupiter's magnetic field is profoundly different from that of all other known planets — it essentially has two magnetic south poles instead of just one, a new Nature study finds.

The magnetic field of 1200 Tesla is produced for a brief moment and in a small volume. I'd expect a lot more work before this can be applied to tokamak-style fusion, and they don't claim anything ...
