Abstract : A MAJOR ADVANCE IN THE FIELD OF APPLIED MAGNETISM. The unique properties of these materials promise to revolutionize the design of devices employing permanent magnets. However, as with all new advances in material science, criteria must be established to effectively incorporate the inherent advantages existent within these new materials. Consequently, certain device configurations are not conducive to the incorporation of the new rare-earth cobalt materials. Such a limitation is illustrated in the first design considered; the flux modulation generator which employs conventional Alnico material. The second design discussed in detail is the moving-coil generator employing Co5Sn or Co5Ce material. Both devices may be used to convert mechanical motion into electrical energy and are applicable to improving the power output of existing fluidic generators used to power artillery and rocket fuzing systems. Theoretical predictions are given and alternator configurations are suggested for improving generator performance. (Author)
