GENERALIZATION OF COWLING THEOREM
An extension of Cowling's neutral point arguments shows that no axisymmetric poloidal magnetic field can be maintained by self-exciting dynamo action in an electrically-conducting fluid against the dissipative effects of Ohmic heating. This generalizes previous results to cases where the magnet...

| description | An extension of Cowling's neutral point arguments shows that no axisymmetric poloidal magnetic field can be maintained by self-exciting dynamo action in an electrically-conducting fluid against the dissipative effects of Ohmic heating. This generalizes previous results to cases where the magnetic field can be non-steady, the fluid compressible and the (scalar) coefficient of magnetic permeability and electrical conductivity dependent on position and time.-Authors |
