Ohm's law for mean magnetic fields

The magnetic fields associated with plasmas frequently exhibit small-amplitude MHD fluctuations. It is useful to have equations for the magnetic field averaged over these fluctuations, the so-called mean field equations. Under very general assumptions, it is shown that the effect of MHD fluctuations on a force-free plasma can be represented by one parameter in Ohm's law, which is effectively th...

Magnetic Reconnection Solutions Based on a Generalized Ohm’s Law

It is known that exact magnetic reconnection solutions can be constructed for collisionally dominated resistive plasmas. In this paper we refine the collisional resistive description by invoking an Ohm’s law that includes Hall current and plasma inertial contributions. We first demonstrate the surprising fact that the analytic treatment of both two and three dimensional current sheet reconnecti...

Does the interstellar magnetic field follow the Chandrasekhar - Fermi law ?

We carried out 1.25 pc resolution MHD simulations of the ISM – including the large scale galactic fountain – by fully tracking the time-dependent evolution of the magnetic field and the formation of shock compressed regions in a supernova-driven ISM. The simulations show that large scale gas streams emerge, driven by SN explosions, which are responsible for the formation and destruction of shoc...

On The Magnetostatic Inverse Cube Law and Magnetic Monopoles

It can be demonstrated experimentally that interaction between magnetostatic fields for which both poles geometrically coincide obeys the inverse cube law of attraction and repulsion with distance (far fields interaction law) which proves by similarity that localized (in the sense of behaving as if they were point-like) electromagnetic elementary particles must obey the same interaction law sin...
