उत्तर
| Properties | Dia | Para | Ferro |
| Magnetic susceptibility | Negative | Positive and small | Positive and large |
| Relative permeability | Slightly less than unity | Greater than unity | Large |
| Nature of magnetic field lines | Repelled or expelled from diamagnetic materials | Attracted into the paramagnetic materials | Strongly attracted to the ferromagnetic materials |
| Susceptibility | Temperature independent. | Inversely proportional to temperature. | Inversely proportional to temperature. |
| Examples | Bismuth, copper, and water, etc. | Aluminum, platinum, chromium, etc. | Iron, Nickel, and Cobalt |
