Abstract

To increase the output amplitude obtained from Wiegand wire transducers, for example of the type used in contactless ignition breaker systems, a flux concentration or flux guide element (3) of highly permeable material, for example high-frequency ferrite core material, is provided surrounding the Wiegand wire (1) and, at least in part, the pick-up coil (2) coupled thereto.
