We generated a sample of 409 AGNs for which both the radio luminosity at 5GHz and the line luminosity in [OIII] 5007 have been measured. The radioluminosity spans a range of ten orders of magnitude, and the [OIII] lineluminosity spans a range of eight orders of magnitude --- both considerablylarger than the ranges in previous studies. We show that these two quantitiesare correlated in a similar way for both radio-loud and radio-quiet AGNs. Wedemonstrate that the observed correlation can be explained in terms of a modelin which jets are accelerated and collimated by a vertical magnetic field.Comment: 45 pages inc. 7 figures, 1 table of 15 pages in ps-format.
