  In paper I, we have studied the conditions under which flux tubes are
expelled from adiabatic thick accretion disks. In the present paper, we explore
a few other models of thick disks, where flux tubes could be stored. We show
that flux tubes with sufficiently weak fields are not expelled out if they move
adiabatically inside an isothermal disk; they continue to oscillate around mean
equipotential surfaces inside the disk. If the field in the flux tube is
amplified due to the shear, they are eventually expelled away. We explore a
`toy' model also, where the entropy increase outwards from the center of the
thick disk and find a similar behavior. Flux storage in the disk, as in the
case of the sun, in general, enhances the possibility of sustained magnetic
activity formation of coronae in the chimney region. The existence of coronae
on the disk surface may explain the short-time variability in the spectra of
Blazars and the emission of energetic particles from AGNs and Quasars. It may
also supply matter to the cosmic jets through magnetized winds.
