We use the Polyakov loop coupled quark-meson model to approximate low energy QCD and present results for the chiral and deconﬁnement transitions in the presence of a constant magnetic background B at ﬁnite temperature T and baryon chemical potential µB. We investigate eﬀects of various gluonic potentials on the deconﬁnement transition with and without a fermionic backreaction at ﬁnite B. Additionally we investigate the eﬀect of the Polyakov loop on the chiral phase transition, ﬁnding that magnetic catalysis at low µB is present, but weakened by the Polyakov loop.
