Ampere Repulsion and Graneau?s Exploding Wires

Paul Wesley
Year: 1987
Keywords: Ampere Repulsion, Graneau Experiment

Graneau has claimed that Ampere repulsion between collinear current elements is responsible for the rupturing or explosion of wires carrying high currents without, however, providing a valid theoretical estimate of the Ampere tension involved. The present paper shows that a correct estimate of the Ampere tension supports Graneau?s claim. In addition, it is shown theoretically that no electromagnetic pinch effect exists for a solid metal; so the pieces of wire that Graneau obtains could not have been pinched off. PACS number.41.10.
