What is the typical order of strength of the magnetic field in Gauss in a black hole Accretion Disk?

It may be a binary black hole accretion disk or an AGN.

Thank you very much Sriram for the paper link you shared. The reported value of 33 G for V404 Cygni is significantly low. The paper itself mentions that the for other sources such as Cyg X-1, the range of magnetic field is ~10^5 to 10^7 G (My theoretical paper also suggests that this range of magnetic field can be acheived in a magnetically supported disc around a black hole.
