Negative magnetic pressure as a trigger of large-scale magnetic instability in the solar convective zone Academic Article uri icon


  • If small-scale magnetic fluctuations are generated in a medium subject to MHD turbulence, the total (hydrodynamic+ magnetic) turbulent pressure will drop; and if the turbulence has become thoroughly established, this effect may reverse the sign of the large-scale magnetic force in the medium, rendering the large-scale field unstable.
