Abstract
A sensor element for testing a planar data carrier having a spin resonance feature. The sensor element comprises a magnetic core having an air gap, and at least one dividing gap, along which the magnetic core is divisible into two or more parts. The sensor element includes a polarization device for generating a static magnetic flux in the air gap. The magnetic core has at least one magnetic potentiometer switchable between two states. A first state has a first magnetic reluctance and, in the first state of the magnetic potentiometer, the sensor element is set up for a measurement on a spin resonance feature of a data carrier introduced into the air gap, A second state has a second, different magnetic reluctance and, in the second state of the magnetic potentiometer, the sensor element is set up for a division of the magnetic core along the dividing gap.
