The magnetic susceptibility of high-(Formula presented) superconductors is investigated in the normal state using a coupled bilayer model. While this model describes in a natural way the normal-state pseudogaps seen in (Formula presented)-axis optical conductivity on underdoped samples, it predicts a weakly increasing susceptibility with decreasing temperature and cannot explain the magnetic pseudogaps exhibited in NMR measurements. Our result, together with some experimental evidence, suggests that the mechanism governing the (Formula presented)-axis optical pseudogap is different from that for the (Formula presented)-(Formula presented) plane magnetic pseudogap.
