Dear Student,
If the magnetic susceptibility is positive, the material can be paramagnetic, ferromagnetic or antiferromagnetic. ... Alternatively, if the magnetic susceptibility is negative, the material is diamagnetic and as a result, the magnetic field is weakened by the presence of the material.​diamagnetics and other types of magnetism. If χ is positive, a material can be paramagnetic. In this case, the magnetic field in the material is strengthened by the induced magnetization. Alternatively, if χ is negative, the material is diamagnetic.zinc is diamagnetic
