The purpose of the Fluxus‐1 and ‐2 active experiments is to study plasma jets injected parallel to the magnetic field and to study the interaction of these jets with the magnetic field. The experiments were conducted using a shaped‐charge device, known as an explosive type generator (ETG), that produced an artificial aluminum plasma jet. In Fluxus‐1 and ‐2 the jet was injected nearly parallel to the geomagnetic field at an altitude of 140 km toward an instrumented diagnostic payload located about 100 m away from the ETG. A ∼50% reduction in the magnetic field was observed as the plasma jet passed by the diagnostic payload. Comparisons of 3‐dimensional simulation results with the observed magnetic field perturbations suggest that the Fluxus‐1 plasma jet was ∼30° from the magnetic field direction while the Fluxus‐2 plasma jet was directed nearly parallel to the magnetic field.
