Auf eine Metallplatte P treffen viele parallele Elektronenstrahlen.
Innerhalb der Metallplatte gibt es magnetische Bereiche (sog. Wei{\ss}sche Bezirke),
deren Orientierung (senkrecht zur Zeichenebene) eingezeichnet ist.
Unterhalb der
Metallplatte befindet sich eine Folie, die leuchtet wenn Elektronen auf sie treffen.
Skizziere den Weg der Elektronen zwischen P und der Folie und den Helligkeitsverlauf der
sich in der Folie ergibt.
