Three-dimensional structures of electromagnetic fields in low-inductivity store buses and in magnetic system components

Estimates made within the framework of a hydrodynamic model show that for generation of electromagnetic fields with induction near to 103 T in single-turn coils of a small size sources of energy are necessary supplying current of the order of 107 A with the rise time of the order of 10-7 s. Current-carrying circuits of such sources should have rather low inductivity. Therefore the typical elements of the the circuits are conductors separated by narrow insulating gaps, single-turn coils, flat sheets with slits characterized by strong skin-effect. The analysis of current distribution in the systems under consideration is important both for calculation of inductivity and for estimation of the coil geometric factor (relation of induction to current) and the degree of the field uniformity in the coil
