A magnetic detacher has a core magnet and a ring magnet. The core magnet has a body with a top and bottom surface, and produces a first magnetic field. The ring magnet defines a cavity. The ring magnet has a body with a top and bottom and produces a second magnetic field. The ring magnet is axially aligned with the core magnet such that the first magnetic field opposes the second magnetic field along the bodies and enhances it within the cavity. The top surface of the core magnet is separated from the bottom surface of the ring magnet by a predetermined distance thereby producing a resultant magnetic field having a first resultant field strength at a specific position greater than a second resultant field strength produced at the same position when the top surface of the core magnet abuts the bottom surface of the ring magnet.
