Magnetic field
Magnetic field is a physical field produced by moving electric charges and intrinsic magnetic moments. In astrophysical contexts, magnetic fields influence plasma behavior, particle motion, and energy transport.
Magnetic fields are discussed in physics, astrophysics, and plasma physics.
Status
Magnetic fields are observed and inferred in planets, stars, galaxies, and interstellar space. Their generation, structure, and role in large-scale dynamics are studied through observation and theoretical modeling.
