Abstract
The radial transport of magnetic flux in CV accretion disks is considered. Turbulent diffusion in a disk with finite outer radius R d leads to decay of large-scale magnetic fields, as magnetic flux can leak out at the outer edge of the disk. Numerical computations of the decay rate and magnetic structure are presented. It is shown that the decay time is of order R d /(α C S ), significantly shorter than the accretion time, R d /| v r | (here C S is the sound speed at the outer edge of the disk and α is the viscosity parameter). Centrifugally driven winds may be possible from the outer parts of the disk provided there exist efficient dynamo processes which regenerate the field.
