Abstract
This paper reviews the underlying physics of the dynamics of magnetic field in a fluid with large electrical conductivity. The magnetic field is highly non-dissipative in a a highly conducting fluid at large length scales and at the same time the field is highly dissipative at small length scales. The dynamics of magnetic field in between these two scales shows ubiquitous phenomena like generation of magnetic discontinuity and topological rearrangements of magnetic field lines. Such diverse dynamics of magnetic field then provides an opportunity to understand the real physical systems like solar corona , interplanetary medium, laboratory plasmas, etc.
