Many models for anomalous transport consider the turbulent E × B transport arising from electrostatic micro-instabilities. In this paper we investigate whether the perturbed magnetic field that is associated with such instabilities at small but finite values of ß can lead to significant stochastic magnetic field transport. Using the tearing parity, long wave-length ion temperature gradient (ITG) modes in a plasma slab with magnetic shear as an example, we calculate the amplitude of the perturbed magnetic field that results at the resonant surface for the case when the plasma dissipation is given by the semi-collisional electron model. The resulting stochastic field transport is estimated and also compared with an estimate for the E×B transport due to the ITG mode.
