Abstract

V originále

Using general relativistic magnetohydrodynamics simulations we study evolutionof accretion torus around black hole endowed with five different initial magneticfield configurations: contour, loop, parabolic, monopole, uniform. Due to accretion of material onto black hole, parabolic magnetic field will develop in accretion torusfunnel around vertical axis, while turbulent and chaotic magnetic field insideaccretion torus will redistribute angular momentum inside torus and create corona around it.
