We show that the generally held belief that field‐aligned electron velocities associated with the corresponding currents can be ignored is unfounded in the case of magnetic pulsations. These field‐aligned velocities contribute significantly to two of the three mechanisms identified in the earlier work. Diagrams are presented to compare our results with those previously obtained by us and other workers using various simplifying assumptions.</jats:p>"}]}],"creator":[{"@id":"https://cir.nii.ac.jp/crid/1380848661784571397","@type":"Researcher","foaf:name":[{"@value":"P.
