The discovery of magnetic fields on the Sun made by George Ellery Hale in 1908 (1) is undoubtedly one of the most outstanding events in the astronomy of this century. It is well worth mentioning that the geomagnetic field was a unique example of cosmical magnetic fields before this discovery. But during the last two decades, it became known through Babcock’s work (2) that numerous stars have also magnetic fields amounting to several thousand gauss on the average over the star’s surface and thus considerably exceeding solar magnetic fields concentrated mainly in sunspots.
