Abstract

The evidence of cosmic magnetism is examined, taking into account the Zeeman effect, beats in atomic transitions, the Hanle effect, Faraday rotation, gyrolines, and the strength and scale of magnetic fields in astrophysics. The origin of magnetic fields is considered along with dynamos, the conditions for magnetic field generation, the topology of flows, magnetic fields in stationary flows, kinematic turbulent dynamos, the turbulent dynamo in a disk, topics in nonlinear turbulent dynamo theory, stellar cycles, the galaxy and its magnetic field, the galactic dynamo, the role of magnetic fields in star formation, magnetic fields in cosmology, accretion on black holes, and strong magnetic fields. Attention is given to frozen-in magnetic fields, a relict field hypothesis, the random walk of fluid particles, the problems of stellar taxonomy, evidence of stellar activity, the stochastic nature of the prolonged weakening of solar activity, the evolution of magnetic clouds, pulsars, and the problem of magnetic charges, referred to as 'monopoles'.
