Magnetic fields as a research area encompasses theoretical, computational, and experimental studies of magnetic field generation, structure, dynamics, and interaction with matter across scales, from condensed-matter systems to astrophysical and cosmological environments. It includes investigation of classical and quantum magnetostatics and electrodynamics, dynamo processes in plasmas and fluids, magnetohydrodynamics, and spin- and orbital-derived magnetism in materials. Research addresses field topology, reconnection, turbulence, confinement, and transport, as well as applications in magnetic resonance, spintronics, fusion devices, particle accelerators, space weather, and precision metrology, often integrating advanced diagnostics, numerical simulations, and multi-scale modeling.
While Jupiter's Great Red Spot has been a constant feature of the planet for centuries, University of California, Berkeley, astronomers have discovered equally large spots at the planet's north and south poles that appear ...
