Magnetic properties of weak magnetic minerals
The magnetic properties of pure weak magnetic minerals are different from those of ferromagnetic minerals. The magnetic susceptibility of ferromagnetic minerals is variable, while the magnetic susceptibility of weak magnetic minerals is constant. It has nothing to do with external magnetic field strength, particle size and shape, but only with mineral composition. There is also no remanence and hysteresis. Magnetic weakly magnetic minerals weaker, less than the susceptibility, it is easy to study a small number of magnetic minerals, such as hematite artifacts, titanium, iron ore is also owned by the weakly magnetic minerals, weakly magnetic minerals even at high external magnetic field, It is also not easy to achieve magnetic saturation.
