We propose to determine the field strength of a sample of magnetic cataclysmic variable stars in which the field strengths are expected to be in the range 2-10MG. Until now only 2 stars in this group have had their field strengths determined, (to within a factor of 2). An accurate determination of the magnetic field strength of these systems is important in a number of ways: Firstly, recent high quality spectra obtained using ASCA has opened up a new era of observational astronomy in these objects. However, to model their spectra fully, an accurate determination of their magnetic field strength is necessary. Secondly, the accretion flow onto the white dwarf is influenced by the magnetic field. An accurate magnetic field strength is necessary to fully model the accretion flow. Thirdly, the magnetic field strength of the these objects is also needed to make progress in understanding the evolution of magnetic CVs - an area of particular contention at present.
