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.
Mercury was long considered the exception to the rule that magnetic planets have radiation belts similar to Earth's Van Allen belts, but a new study by University of Michigan Engineering and the University of California, ...
