Abstract
The present invention describes a release mechanism () for releasing magnetically releasable anti-theft devices consisting of a multiplicity of permanent magnets in the form of a Halbach array, which are disposed on a plane. While the highly magnetised top side () of the release mechanism () is covered by the cover plate () on the release side, a base plate () used for mounting or support is located on the underside () of the release mechanism (). The permanent magnets encompass a continuous, self-contained frame magnet (), which is magnetised in an axial direction and has a first recess. Inserted in this first recess is a segmented magnet (), wherein the individual segments are magnetised perpendicularly to the magnetization direction of the frame magnet () and a second recess is left open, in which an axially magnetised magnetic core () is inserted.
