Investigating solar corona structures has led Paul Bellan, Caltech professor of applied physics, and his former graduate student Yang Zhang (Ph.D. '24) to discover a new equilibrium state of the ...

Numerous test-and-measurement applications require a high-frequency magnetic field. Oftentimes, high field strength is needed. Examples of such applications include bio-medicine research on the ...

Researchers recently discovered that the strength of the magnetic field required to elicit a particular quantum mechanical process corresponds to the temperature of the material. Based on this ...

A public‑private partnership between Commonwealth Fusion Systems (CFS), the U.S. Department of Energy's (DOE) Princeton Plasma Physics Laboratory (PPPL) and Oak Ridge National Laboratory has led to a ...

They calculated that creating these magnetic fields in the real world would require a laser system with a pulse energy of 0.1 to 1 kilojoule and a total power of 10 to 100 petawatts.

For reference, the Earth's magnetic field is around 0.5 gauss, and a typical refrigerator magnet ranges from 50 to 100 gauss. The research is detailed in the journal Science today (Dec. 7).
