  The quark gap equation under the rainbow truncation, with two versions of a
phenomenological one-gluon exchange interaction and in the presence of a
uniform magnetic field is considered. It is argued that in order to describe
the quark condensate in the limit of vanishing magnetic fields, one must sum
over the Landau levels. The resulting chiral quark condensate rises
quadratically for small magnetic fields and linearly for large fields, in
qualitative agreement with various recent lattice results. It is observed that
when discussing quarks, the magnitude of the magnetic field must be considered
relative to the scale of the strong interaction.
