  We present a magnetic stripping model for AM Her type objects. Our model is
based on an equilibrium condition between ram pressure and magnetic pressure in
a stiff dipolar magnetic field. We investigate the detailed geometry of the
stripping process, most of which can be tackled analytically. By involving
additional numerical calculations, the model allows the prediction of
phase-resolved spectra and Doppler tomograms. The emission line features from
the companion star, the horizontal stream and the accretion curtain are
identified with the emission line components found by Gaussian fitting to
observational data of HU Aqr in its high accretion state. Given the simplicity
of the model, its agreement with the observation is remarkably good and enables
and radii, total mass accretion rate, bulk temperature, and coupling density.
