Abstract: Magnetic fields may effect the supernova explosion of a massive star dynamically, e.g., accelerating jet-like outflows, if they are amplified sufficiently from their weak progenitor strength. In the presence of rotation, the magneto-rotational instability might account for the required amplification. In a parameter study of simplified models of supernova cores, we have explored this possibility. I will summarise the main results of this study, suggesting magnetic fields to play a role for a subclass of explosions, and give an outlook on open issues in this field.
