Abstract

See full text

A magnetic material having dual properties and a manufacturing method thereof are disclosed. The magnetic material having dual properties consists of: 5% to 88% of a permanent magnetic material, 5% to 88% of a soft magnetic material, 6% to 16% of a binder, and 1% to 10% of an auxiliary agent. The magnetic material having dual properties manufactured by mixing two phases without microscopic intergranular exchange coupling interaction has unexpected effects: the range of a magnetically attracted object is expanded to include a magnet having dual properties; the range of a magnetically attractive object is expanded to include a magnet having dual properties; the minimum value of the magnetic attraction force is increased, the magnetic attraction force is more uniform, and it is smoother to move and rotate an object. The effect obtained by two layers of the soft magnet and the permanent magnet can be realized by a single layer structure of the magnet having dual properties.
