Magnetic Properties based on the behavior of substances when placed in the magnetic field, they are classified into five classes.
Table: Magnetic properties of solids
| Properties | Description | Alignment of Magnetic Dipoles | Examples | Applications |
| Diamagnetic | Feebly repelled by the magnetic fields. Non-metallic elements (excepts O2, S) inert gases and species with paired electrons are diamagnetic | All paired electrons | TiO2, V2O5, NaCl, C6H6(benzene) | Insulator |
| Paramagnetic | Attracted by the magnetic field due to the presence of permanent magnetic dipoles (unpaired electrons). In a magnetic field, these tend to orient themselves parallel to the direction of the field and thus, produce magnetism in the substances. |
At least one unpaired electron |
CuO,O2 Cu2+, TiO2 VO, VO3 |
Electronic appliances |
| Ferromagnetic | Permanent magnetism even in the absence of magnetic field, Above a temperature called Curie temperature, there is no ferromagnetism. |
Dipoles are aligned in the same direction |
Fe, Ni, Co, CrO2 | CrO2 is used in audio and video tapes |
| Antiferromagnetic | This arises when the dipole alignment is zero due to equal and opposite alignment. | MnO, MnO2, Mn2O, FeO, Fe2O3; NiO, Cr2O3, CoO, Co3O4, | – | |
| Ferrimagnetic |
This arises when there is net dipole moment |
Fe3O4, ferrites | – |
