Abstract
This study indicates that although large electric fields, with durations of the order of seconds, can be generated during a detonation, the magnetic field associated with this electric field does not appear to be significant. Augmentation of the field with an external magnetic coil does not produce the desired increase in the magnetic component nor serve to enhance the duration. This latter lack of effect is most likely due to the rapid recombination of charged particles, ions and electrons in the expanding detonation products cloud. Enhancement of existing (initial pulsed) fields was of the order of 5 x 10-5 T, approximately 1.2-2 times the initial field strength. There were some indications that the addition of carbon served to increase the EMP slightly relative to the initial NM/A1 mixture. However, it may be that the NM/A1 slurry is a relatively optimum mixture for this type of approach. In all cases the duration of the explosive event did not exceed 300 microseconds.
