Abstract
Magnetic retainer, characterized in that a ferromagnetic plate (2) is located on a surface of the magnetic pole of a permanent magnet (1), having a drilled hole (1a) from the surface of a magnetic pole, while a shielding plate magnetic (3) is located on the other magnetic polar surface, said permanent magnet (1), said plate (2) and said plate (3), coupled and fixed to a cylindrical box formed of a non-magnetic material, then arranging a ferromagnetic plate (7), magnetically separable, located in contact with the plate (3), while there is a ferromagnetic rod (8), projected from the plate (7) and separable magnetically through the magnetic hole (1a).
