説明
<jats:p>An exact solution is given (apart from the neglect of displacement‐currents) for the motion and electromagnetic fields of a uniform neutral ionized distribution of ions and electrons initially situated on an indefinitely long circular cylindrical surface, and projected radially inwards towards the axis of the cylinder, in the presence of a permanent magnetic field which is everywhere parallel to the axis, and varies in intensity as the inverse cube of the distance from the axis. It is shown that the ions and electrons will remain “united,” that is to say, will continue to lie on one cylindrical surface, if the total ionic (or electronic) charge exceeds a certain lower limit; an electric current will be induced, flowing round the cylindrical surface and increasing the magnetic intensity within the cylinder. The problem is discussed as one which partly illustrates the first phase of a magnetic storm, and, in particular, the sudden increase of <jats:italic>H</jats:italic>, during only a few minutes; it clearly shows that when a neutral ionizing stream advances into regions of increasing intensity in a magnetic field, the electrostatic attraction between the ions and electrons can carry the electrons forward far beyond the distances they could attain alone, if the stream is sufficiently dense.</jats:p>
