We present a numerical study of the formation of electric current sheets and magnetic flux ropes during emergence of flux into the solar corona. Using analytical initial states in which a new flux has emerged into a corona containing a preexisting flux system of the opposite polarity, we study the dynamical interaction between the two flux systems using the ZEUS MHD Codes. We find that the initially smooth interface between the opposite flux systems quickly steepens into a current sheet which immediately leads to magnetic reconnections and changes in magnetic topology. Magnetic flux ropes formed out of the reconnected fields. The ratio of the emerging flux to the preexisting flux is a discriminating physical factor. If this ratio is below some critical value, the flux rope produced will stay in some quiescent state in the atmosphere. If this ratio is sufficiently high, the flux rope produced will rise through the atmosphere and escape from the computational domain. These numerical results corroborate our recent theoretical studies which will be briefly summarized (Zhang and Low 2002, 2003, 2004).
