A class of density enhanced, electromagnetic-pulse-compacted, bonded permanent magnets having the following properties: a. maximum energy product (BH)max up to 40% greater than that of traditional, mechanical, compacted, bonded permanent magnets, b. (BH)max up to 99% of theoretical, c. a void ratio approaching 0 volume %, d. use temperatures from room temperature up to about 550° C., and e. a structure, wherein: a mixture of permanent magnet particulates and a binder is compacted by pulsed electromagnetic forces, where each pulse has a pulse time less than the thermal time constant of the permanent magnet particulate, and said compaction is achieved without adversely affecting the binder or the structure of the permanent magnet particulate.
