Abstract

1. Coil arrangement with a magnetically saturable core surrounded by a coil and a permanent magnet arrangement, wherein the permanent magnet arrangement and the core are one adjustable relative to the other for the variable polarisation of the latter, characterised thereby, that the permanent magnet arrangement consists of a single permanent magnet (3) kept at a spacing from the saturable core while forming an air gap (4) and the width of the air gap (4) is adjustable.
