We introduce and discuss the basic features of a new numerical code designed to handle ideal MHD flows in dynamical spacetimes in general relativity, and particularly designed to investigate the gravitational collapse of the core of massive stars leading to neutron stars or black holes. After introducing the mathematical framework for the general relativistic MHD equations and the Einstein equations (within the so-called conformal flat condition) we present results from two representative simulations of magneto-rotational stellar core collapse. Our simulations highlight the importance of genuine magnetic effects such as the magneto-rotational instability on the dynamics of the process.
