parallel zur Längsachse der Platte verlaufen. so stellt sich dieselbe mit ihrer Querachse in eine bestimmte Richtung ein, welche abhängig ist von der Form derjenigen Fläche, über die sich das magnetische Feld ausbreitet.
In Fig. 1 ist M ein permanenter Magnet. P ein in dem Magnetfelds um seine Längsachse drehbares Plättchen, an dem ein Zeiger Z befestigt ist. Die magnetischen Kraftlinien gehen vom oberen Schenkel des Magneten aus und durchsetzen das Plättchen P. Es zeigt sich nun, dass bei der dargestellten Form des Magneten das Plättchen sich mit seiner Querachse senkrecht zur

Durch passende Anordnung von Spulen lassen sich die verschiedensten Wirkungen auf das Plättchen hervorbringen, so dass dasselbe jede gewünschte Bewegung awfführt. Dabei hat man es ganz in der Hand. durch Wahl der ursprünglichen Feldausdehnung dem Plättchen eine

run parallel to the longitudinal axis of the plate. so the transverse axis adjusts itself in a certain direction, which depends on the shape of the surface over which the magnetic field spreads.
In Fig. 1, M is a permanent magnet. P a small plate which can be rotated about its longitudinal axis in the magnetic field and to which a pointer Z is attached. The magnetic lines of force emanate from the upper limb of the magnet and penetrate the plate P. It can now be seen that in the shape of the magnet shown, the plate is with its transverse axis perpendicular to the

A suitable arrangement of coils can produce a wide variety of effects on the platelet, so that it can perform any desired movement. It's entirely up to you. by choosing the original field size the plate one
