Abstract:

The contraction of plasma around a neutral point of a magnetic field may be connected with pinch effect, arising at the approach of two force tubes and the annihilation of their azimuthal fields. The possibility of such contraction at a rapid change of the sunspot field is discussed, assuming that this field is of a dipole charac ter. In both cases, the conception of strong shock waves converging at the neutral point is indicated. Near this point the incident shock wave is not hydromagnetic, and its front outruns the magnetic wall - the region of a strong field which moves together with the main mass of plasma behind the front. After reflection in the neutral plane, the front of the reflected shock moves in the contracting plasma and a more or less steady high-temperature plasma is formed be hind this front. The high-temperature plasma obtains its energy from magnetic energy losses connected with the contraction of the plasma. The reflected shock may check or stop the con tracting wall, so that expansion or pulsations can set in instead of contraction. Author
