Abstract

Results of an experimental study of the generation of high-current pulses in a moving magnet system based on an open ferromagnetic circuit design are presented. The magnet was accelerated with the use of a light gas gun. Experimental data are given for the output high current pulses, output voltage, and power delivered in the load for different types of pulse-generating coils. The effect of various pulse-generating windings is given. It has been shown that the Nd₂Fe₁₄B hard ferromagnetic projectile (diameter 2.54 cm and height 1.9 cm) moving with a velocity of 320 m/s is capable to produce in the pulse-generating coil a current pulse with amplitude of 1.4 kA and a full-width at half-maximum 80 μs.
