Resumen:
We have computed theoretical He I line profiles by means of LTE models for the photosphere of B stars. In these models we have introduced a Lorentz force in the equation of hydrostatic equilibrium following the steps of Valyavin et al. (2004, A\&A 420, 993). We analize the capacity of a magnetic field to modify the line profile. This mechanism can explain the variations in line profile and the stability of the continuum in He variable stars and can be useful for the determination of abundances in magnetic stars.
