The cylindrical magnetic flux compression by explosive implosion (MC-1) is a kind of unique high energy density dynamic technique. A metal cylinder was driven by explosive implosion to compress the primary magnetic flux inside and an ultrahigh magnetic field was realized, which could be used to achieve effective isentropic compression of the sample. This technique has anigue characters like ultrahigh isentropic pressure and ultrahigh magnetic field, and would find wide usage in areas like high pressure physics, new material synthesis and ultrahigh magnetic field physics. The Institute of Fluid Physics, Chinese Academy of Engineering Physics (IFP, CAEP) has begun to make experiments on MC-1 since 2011 and a one-stage MC-1 set-up has been built up. The primary experimental results including the movement of liner and typical turn-around character in MC-1 experiment were observed and recorded. In the experiment a dynamic magnetic field of about 430T was obtained. The MC-1 process was numerically simulated by the one-dimensional MHD code and the simulations are in accord with experiments. Numerical simulations show that this technique has advantages in isentropic compression of materials as compared with normal implosion experiment.
