    "abstract": "In this paper, two classes of exact analytic time-dependent soultion of\nmagnetic annihilation for incompressible magnetic fluid, have been obtained by\nsolving the magnetohydrodynamic (MHD) equations directly. The solutions derived\nhere possess scaling property with time $t$ as the scale factor. Based on these\ntwo solutions, we find that, for some given inflow fields, the evolution of the\nannihilating magnetic field can be described by the solutions of certain\nordinary differential equations whose variables are dilated simply by time $t$.\nThe relevant evolution characteristics in the process of magnetic annihilation\nare also revealed.",
