The Magnetic Field

The discontinuity surfaces across which the only discontinuities in the derivatives of flow variables exist are known as singular surfaces. The influence of a magnetic field on the propagation of singular surfaces in an isothermal flow of gas is investigated. We find that the expansive waves ultimately disperse while compressive waves grow into a shockwave in a finite time. The derivation of the shock-wave formation time and its dependence on the magnetic-field intensity reveal interesting differences between outward- and inward-moving singular surfaces. In the particular cases of plane and cylindrical singular surfaces, the shock-wave formation distances and times have been derived.

Detailed measurements of the trapped magnetic fields and currents in plasma structures generated by conical theta-pinches are reported. Studies of these structures interacting with a magnetic barrier, and with each other in a collision at the centre of a magnetic mirror, are reported. The magnetic well formed by the collision has been studied by simultaneous use of several diagnostic techniques. The measurements are in agreement with a force-free, collinear magnetic field configuration (Wells 1972). Arguments relating superposability and collinearity of flow fields to these observations are given.
