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.
A flower-shaped structure only a few micrometers in size made of a nickel-iron alloy can concentrate and locally enhance magnetic fields. The size of the effect can be controlled by varying the geometry and number of "petals."
