Abstract

PURPOSE:To obtain an engaging tool having excellent magnetizing property by abutting a ferromagnetic plate and a ferromagnetic plate integrally molded with a plastic magnetic substance through a ferromagnetic member projected from either of the integral substance. CONSTITUTION:The blank of a permanent magnet is used as the plastic magnet 1, the ferromagnetic plate 3 focussing the magnetic field of one magnetic pole surface 1b of the magnet 1 is buried into the magnet 1 or molded integrally so that one part is buried in the magnetic pole surface 1b, and the line of magnetic force in the magnetic pole surface 1b is focussed. The other side end of a ferromagnetic lever 3a continuously mounted to the plate 3 is formed simultaneously so as to be approximately projected from the other magnetic pole surface 1a. In such an engaging tool A, the line of magnetic force in the magnetic pole surface 1b is focussed to the plate 3, and guided to the magnetic pole surface 1a through the lever 3a. On the other hand, the abutting tool B consisting of the ferromagnetic plate 2 forms a magnetic field in the magnetic pole surface 1a, and is abutted detachably with the end of the lever 3a.
