Abstract

Es wird eine einstellbare Spule für die Linearisierung der Zeilenablenkung von Bildschrimgeräten beschrieben, die einen Spulenkörper 1, eine Wicklung 8, einen von der Wicklung umgebenen sättigbaren Spulenkern 7 und einen Permanentmagneten 10 zur Vormagnetisierung des Spulen­ kerns 7 aufweist und deren Besonderheit darin besteht, daß zwischen dem Permanentmagneten 10 und dem Spulen­ körper 7 ein Luftspalt 11 eingestellt und hinsichtlich seiner Breite den jeweiligen Erfordernissen angepaßt werden kann. Die spezielle Konstruktion erlaubt auch eine kostengünstige Massenherstellung.
