Experimental results using micro-ferromagnetic generators

Several series of tests using explosively loaded ferromagnetic generators to drive inductive coils have been summarized into lessons learned and an outline of best practices for building small FMGs will be presented. Most of these FMGs were built using 25mm diameter, commercially available N50 magnets. All of these experiments were conducted at Redstone Arsenal, AL. Loads representative of flux compression stators were built and used. The long time, tens of microseconds, effects on the inductors were also examined. This paper will summarize over seventy tests with techniques used to mitigate skin losses as well as eddy current losses. A first cut at scaling by linear combination of generators is also shown.
