Abstract The effect of tangled magnetic fields has been included in a new study of full-amplitude models of classical Cepheids. As compared with nonmagnetic models, the magnetic models have longer periods, larger amplitudes, and earlier phases of the small secondary bump that appears on the velocity and light curves. The induced changes of period and of bump phase yield better agreement with observations if Cepheids have normal evolutionary masses. But the predicted amplitudes are larger than those observed; moreover, the inferred value of the mean ratio of magnetic pressure to thermodynamic pressure falls significantly below the value needed to explain the period ratios of the double-mode Cepheids.
