“…The first experiments in wire explosions under very high currents and voltages were made by Nasilowsky during the 60s. At the 80s, Pappas [3], Graneau [4,5] and Rambaut and Vigier [6] repeated similar experiments and argued on the existence of longtitudinal forces beyond the ordinary Maxwellian electrodynamics. Other attempts for a correct explanation [7,8] fail to provide a clear picture of the phenomena in terms of the Maxwell stress tensor.…”

Abstract:A novel method for ionic collisions is presented based on a theoretical analysis of the long-standing wire fragmentation problem. Based on a Maxwellian approach of the transient electrodynamic forces we deduce a theoretical formula of the total effective tensile force. A number of conducted experiments with low energy capacitor bank discharges are also reported with positive results. The new results show the possibility of building solid state ion colliders below the fragmentation threshold using high power electrical pulses with very low energy.

“…He showed that the possibility of an axial component giving a zero net force on the pair could not be tested by experiments with movable parts if the current flow path is closed. The question of the 'correct' force law has since generated many papers, some of the more recent are summarised in [2][3][4][5][6][7][8][9][10]. Various experimental investigations are still being explored [10][11][12][13][14].…”

Action-reaction forces between current-carrying conductors

The direction of the magnetic forces on currents, at right-angles to the conductor, leads to an apparent failure of the action-reaction force balance when applied to the component parts of a current-carrying circuit. The electromagnetic railgun provides an example showing the need for a force in the direction of current flow. These and other applications continue a long-standing debate, originating in Amp" ere's analysis of the nature of the forces on current elements. The paper examines the consequences of Maxwell's 'dynamical' approach to currents in terms of 'electrical fluids'. The conductor surfaces transfer the transverse force on the conduction electrons to the crystal lattice but, since there are no similar constraints in the axial direction, a current element cannot be treated as a single entitity. The implications of the separation into two groups of charge are examined. It is shown that the hydraulic fluid, or 'hosepipe', analogue provides a useful insight in terms of momentum and pressure. The corresponding electromagnetic properties provide a 'dynamical' alternative to the magnetostatic Maxwell stresses in the field. This also accounts for the reaction in a self-consistent way, but requires such high levels of energy and stress in empty space as to be widely regarded as 'unreal'.
