Abstract
In quark-gluon plasma (QGP), at high temperature the spontaneous generation of color magnetic fields, H^3(T), H^8(T) and usual magnetic field H(T)isrealized.Also,classicalfield−A0(T)condensatedirectlyrelatedtothePolyakovloop−isspontaneouslycreated.ThecommongenerationofbothofthemwithinthetwoloopeffectivepotentialwasinvestigatedrecentlyforSU(2)gluodynamics.ThevaluesofthefieldstrengthsandthemechanismofthemagneticfieldsstabilizationduetoA0(T)havebeendiscovered.Inthepresentpaper,wedevelopfurthertheseinvestigationsinordertofindneweffectsofQGP.Firstofall,wegeneralizetheSU(2)considerationtothefullQCDcase.ThenwecalculatetheinducedcolorchargeQ(ind)3atthebackgroundmagneticfieldH(T)andthecondensatesA03(T).Thefield A_0^8(T) is zero in used two-loop approximation. So, Q_{ind}^8 is zero also. We conclude that magnetic field essentially influences the induced charge compared to the zero field case investigated in \cite{skal21-cond-156}. The extension to other type magnetic fields is given. Key words: spontaneous magnetization, high temperature, asymptotic freedom, effective potential, A0 condensate, effective charge, effective vertexes.
