    In this paper possible magnet systems that can be used in combination with disk-shaped MHD generators are reviewed. The main coil configurations are the single solenoidal magnet and the split-pair magnet. Advantages and disadvantages of these magnet systems are discussed. After an enumeration of a few basic design considerations, a predesign of a split-pair magnet for a compact open disk demonstration unit with a thermal input power of 10 MW is presented. Furthermore, the use of Nb3Sn technology is envisaged to obtain a compact magnet with 9 T in the centre of the MHD channel. The preliminary design configuration consists of a NbTi and a Nb3Sn section. The distribution of winding volume among both sections is based upon minimum conductor costs.
