(1) Compared with ferromagnetic minerals, the value of the specific magnetic susceptibility of weak magnetic minerals is much smaller and does not change with the change of external magnetic field strength. (2) There is no residual magnetism in weak magnetic minerals. (3) The magnetic properties of pure weak magnetic minerals are very weak, but if a small amount of ferromagnetic minerals are mixed therein, its magnetic properties will change greatly. Artifacts are e.g. hematite weakly magnetic minerals, if it remains in the interior of a small amount of magnetite, it will greatly enhance magnetic. This should be especially noted when selecting weak magnetic minerals, especially for selection.

What are the magnetic characteristics of weak magnetic minerals?
There are three points:
