Abstract :
An electrical explosion of a wire in vacuum in very strong external magnetic field is being investigated. It was observed in experiments that at the wire explosion under longitudinal magnetic field with the amplitude about 50T plasma expansion speed was substantially higher then it takes place in traditional geometry where the external field is absent. The azimuthal current appearance was registered by diamagnetic probe. Numeric model that uses the one-liquid hydrodynamic approximation is applied for the experimental data interpretation. Three components of magnetic field are taken into consideration. The transport coefficients being used that are related with the anomalous resistance appearance. The calculations have shown that the observed effect can be described if the model of anomaly of plasma resistance is applied.
