This paper investigates the Cauchy problem for an isentropic magnetogasdynamic system. Under certain reasonable hypotheses on the initial data, we obtain the global existence and uniqueness of the C 1 solution to the system. Meanwhile, when the hypotheses on the initial data do not hold, we obtain the blow-up phenomena of the C 1 solution to the system. The bounds of the solution are shown to depend on the parameter ν, which characterizes a one-dimensional plane flow (ν= 0) or a three-dimensional cylindrically symmetric flow (ν= 1); it is shown that the existence of the finite time singularity is significantly influenced by the magnetic field strength present in the flow along with the initial data.
