Summary

Description
Deutsch: Nachbau: Der erste GMR-Sensor von Prof. Dr. Peter Grünberg in seiner Testvorrichtung. Dieses originalgetreue Replikat wurde von Innomag e.V. - dessen Schirmherr Grünberg ist - im April 2007 auf der Hannover Messe ausgestellt. Das Original ist im Deutschen Museum in München.

An den Enden der Versuchsbank ist jeweils ein zylindrischer Permanentmagnet montiert.

Dazwischen, nahe der Mitte sitzt der schwarze GMR-Sensor oben am Schlitten; von unten greift ein Mitnehmer in die helixförmige Nut (Rechtsgewinde) der Messingwelle ein. Wird diese per Drehknopf gedreht, wird mit dem Schlitten der Sensor verschoben. Je nach Position im inhomogenen Magnetfeld wirkt eine andere Feldstärke und kann ein veränderter elektrischer Widerstand am Sensor gemessen werden. Über den örtlichen Verlauf kann die Abhängigkeit des Widerstands vom B-Feld untersucht werden.
English: Replicate of the first GMR Sensor (black, on top of the slider on the bench, its position between two magnets can be changed) made by Peter Grünberg. The original one is in Deutsches Museum in Munich.
