Abstract: We study some properties of the non-Abelian vacuum induced by strong externalmagnetic field. We perform calculations in the quenched SU3 lattice gaugetheory with tadpole-improved Luscher-Weisz action and chirally invariantlattice Dirac operator. The following results are obtained: The chiral symmetrybreaking is enhanced by the magnetic field. The chiral condensate depends onthe strength of the applied field as a power function with exponent n = 1.6 +-0.2. There is a paramagnetic polarization of the vacuum. The correspondingsusceptibility and other magnetic properties are calculated and compared withthe theoretical estimations. There are non-zero local fluctuations of thechirality and electromagnetic current, which grow with the magnetic fieldstrength. These fluctuations can be a manifestation of the Chiral MagneticEffect CME.
