Query: Magnetic fields and UV-line variability in $\beta$ Cephei   We present results of numerical simulations of wind variability in the
magnetic B1 IVe star $\beta$ Cephei. 2D-MHD simulations are used to determine
the structure of the wind. From these wind models we calculate line profiles
for different aspect angles to simulate rotation. The results are compared with
the observed UV wind line profiles.
