Dynamic of a gas cloud injected across a magnetic field in a collisional plasma

Dynamics of infinite in the direction of the injection of the plasma band in the totally collisonal ionized plasma is considered. The characteristic time of pulse exchange with the background plasma, which exceeds considerably the collisionless time connected with Alfven wave propagation is found. The solution obtained can be used when analysing dynamics of plasma clouds in active cosmic experiments, where appearance of anomalous resistance is possible
