Abstract

The results are presented of tests with compact, explosively driven shock wave ferromagnetic generators. The shock wave from high a explosive charge is passed along the axis of a cylindrical, hard magnet. Two types of permanent magnets were used in the experiments: rareearth NdFeB cylinders (D = 2.5 cm, L = 1.9 cm) and hard ferrite BaFe 2 O 3 cylinders (D = 2.2 cm, L = 2.5 cm). The shock wave demagnetizes the cylinder, reducing the flux from the remnant value to zero. This change in flux generates a voltage in the winding. The current generated in the loads of the generators yielded a peak of 0.75 kA. The operation of the shock wave ferromagnetic generators was analyzed by the Maxwell 3D code. An analysis is given on the specific features of pulse generation in a system like this.
