Abstract
In Part II, the mechanism of the increase of spectral line intensities by application of a homogeneous magnetic field is examined. As a function of arc current, magnetic induction and different combinations of electrodes, a parameter study of Calcium as testing material was made. A dependence of the line-increase from the arc current, the magnetic field strength and the form of electrodes as well as from the ionization potential and the atomic mass of each element was proved. Optimum conditions could be attained. By that a “metastable” arc is formed during the discharge essentially influenced by streaming conditions and the arc rotation. The line-increase itself is based on the intensification of the “cathode-layer”-effect.
