Beschreibung
Zusammenfassung:	The utility model discloses a magnetic button structure for a closed-loop magnetic circuit, which comprises a magnet block and an attraction iron block, wherein the magnet block consists of a pole closed iron sheet and two permanent magnets, the mutually separated permanent magnets are arranged on the two sides of one face of the pole closed iron sheet, the polarity of one of the two permanent magnets respectively arranged on the two sides of the face is a north pole and the polarity of the other one is a south pole, and the faces of the two permanent magnets, which are not arranged on the pole closed iron sheet, are matching faces with the attraction iron block. The structure has the advantages that a large number of magnets can be saved for a magnetic button with same attraction force.
