The observed variation of the magnetic field is compared with that of our model. We search for a relation between the magnetic field and the distribution of the chemical elements. The period in the radial velocities is constant over a time interval of about 100 years.4 pages, 1 figure, to appear in: Proc. of the 26th workshop of the European Working Group on CP stars, eds. P.
