Abstract

RÉSUMÉ. Les déchargesélectriques effectuées avec des fils de titane dans de l'eau créent des monopôles magnétiques. Ceux-ci sont visibles directement ou indirectement par leur action sur des plaques photographiques ou dans les poudres issues des tirs. Ce sont ces effets directs et indirects qui sont passés en revue ici ABSTRACT: Electrical explosions of a titanium wire in water create magnetic monopoles. They are seen directly or indirectly by their effects on photographic plates or by properties of powders resulting from the electrical discharge. These direct and indirect effects are reviewed. We report here results obtained from the trials done at Ecole Centrale de Nantes, comparing with the result of experiments conducted by L. Urutskoev. To be close to his work, our electrical discharges were performed on titanium wires in water. The discharge causes the creation of a plasma and a shock wave, and hence the device is installed within a metal enclosure (Stainless steel /Aluminum) to avoid radiation effects. The device is protected from the discharge by having a polyurethane insulation. This insulation has been covered with a 2 mm layer of Teflon for security measures. The only metal present within this metal enclosure is the Ti40, a high quality titanium. This setup was explained in a previous report of our work [1]. The results must be regarded as partial, provisional. They may be increased if the necessary improvements can be made. However, these results seem sufficiently important from a scientific point of view for us to present them. Direct observation of magnetic monopoles and their traces on film are reported in [2], in this article, we describe our other results
