Balance of energy loss or gain in the disk as a function of radius. The blue, green, red, grey and gold lines show respectively q_Bind (the binding energy gain), q_Adv (the disk internal energy advected energy), q_Rad (the radiative energy loss), L_Wind (energy loss due to the wind) and q_Stress (energy loss or gain due to stresses in the disk). q_Stress changes sign around 4.5 r_g meaning that energy is redistributed from the inner region to the outer regions of the disk by magnetic stresses.
