Effective pion-constituent quark couplings induced by relatively weak magnetic fields are calculated, being that they disappear in the vacuum. In particular, couplings to a scalar and a vector constituent quark currents are investigated. These couplings can correspond to a fluctuation of the neutral pion into a scalar quark-antiquark meson and to a vector meson respectively. Some possible phenomenological implications are discussed.
