We study the response of the QCD vacuum to strong magnetic fields, using a potential model for the quark-antiquark interaction. We find that production of spin-polarized uū pairs is energetically favorable for fields B>Bcrit∼10 GeV2. We contrast the resulting uū condensate with the quark condensate which is present at zero magnetic field, and we estimate the corresponding magnetization as a function of B.
