Abstract
Beta is computed self-consistently in reversed field pinches, using reduced magnetohydrodynamics with transport. Qualitative agreement with the OHTE experiment [Bull. Am. Phys. Soc. 29, 330 (1984)] is found. A derivation of the finite beta reduced equations is presented. The relation of the dynamo effect to anomalous transport is described. The scaling of the δB/B with S is obtained.
