verlaufendes Feld entsteht. Die durch die Spule e n den übrigen Teilen des Zylinderumfanges erzeugten Streulinien werden durch die StabeVgesammeIt, wobei diese selbst zu Magneten werden und zwischen ihren Enden und dem gegenüberliegenden Joch d des Hauptmagneten bei den
Zwischenräumen 9 magnetische Nebenschlussfelder bilden, während über der Mantelfläche der
Spule die indifferenten Zonen dieser Hilfsmagneten liegen, so dass auf dieser Seite des Zylinders i eine magnetische Wirkung nach aussen hin nicht erfolgt.
Die Induktion in dem so gebildeten magnetischen Nebenschluss kann durch entsprechende Dimensionierung der Hilfsmagnete und 'durch entsprechende Wahl des Abstandes 9 ihrer Pole vom Joch d des Hauptmagneten in Grenzen gehalten werden, die das Auftreten von Streulinien auf der Mantelfläche der von den Magnetpolen nicht eingeschlossenen Seite des Zylinders praktisch ausschliessen. In dem in Fig. 2 dargestellten Ausführungsbeispiel bewirken die in gegenläufigem Sinne vom Strom durchflossenen
Spulen e2 die Entstehung eines Folgepoles bei k, während an den Enden kl des Stabes, gleichartige Pole entstehen.
Bei der in Fig. 3 dargestellten Ausführungsform, bei welcher drei Spulen zur Verwendung gelangen, heben sich je zwei nebeneinanderliegende Spulen in ihrer Wirkung auf und das Nebenschlussfeld wird durch die dritte Spule bestimmt. Die Stäbe. f3 werden also hier in ähnlicher Weise magnetisiert wie bei dem in Fig. 1 dargestellten Beispiel.

running field is created. The scatter lines generated by the coil in the remaining parts of the cylinder circumference are collected by the rods, whereby these become magnets themselves and between their ends and the opposite yoke d of the main magnet
Interstices 9 form magnetic shunt fields, while over the outer surface of the
Coil, the indifferent zones of these auxiliary magnets are located, so that there is no external magnetic effect on this side of the cylinder i.
The induction in the magnetic shunt formed in this way can be kept within limits by appropriate dimensioning of the auxiliary magnets and by appropriate choice of the distance 9 of their poles from the yoke d of the main magnet, which prevents the occurrence of stray lines on the outer surface of the side of the not enclosed by the magnetic poles Practically exclude the cylinder. In the embodiment shown in FIG. 2, the effects through which the current flows in the opposite direction
Coils e2 create a subsequent pole at k, while poles of the same type arise at the ends kl of the rod.
In the embodiment shown in FIG. 3, in which three coils are used, two adjacent coils cancel each other out in their effect and the shunt field is determined by the third coil. The bars. f3 are thus magnetized here in a manner similar to that in the example shown in FIG.
