Abstract:
We show that the generally neglected Hall term in the equations for two-fluid magnetohydrodynamics may have a profound effect on α-dynamo action. The new calculation, in addition to subsuming the standard results from the mean field approach, contains a contribution to the α-coefficient entirely due to the Hall current in the microscale.
