The current density fluctuation and magnetic field fluctuation spatial profile were discussed in a high-temperature plasma by using a fast laser-based Faraday rotation diagnostic. It was observed that these fluctuations had characteristics consistent with expectations for resistive tearing modes. The Hall dynamo effect was found to be significant, redistributing (flattening) the equilibrium core current near the resonant surface during a reconnection event. The results suggested that the effects beyond single-fluid magnetohydrodynamics (MHD) were important for the dynamo and magnetic reconnection.
