- Ferromagnetic materials can align themselves parallel to the magnetic field's direction when suspended in an external uniform magnetic field.
- They migrate quickly from the weaker part and move towards the stronger part when suspended in a non-uniform magnetic field.
- They are strongly magnetised in the direction of the magnetic field.
- The external temperature affects the magnetic properties of these substances.
Example:
Some other paramagnetic materials are also listed below in the table.

Important!
A ferromagnetic material, when heated, turns to a paramagnetic material. While heating, the magnetic properties of a ferromagnetic material is altered and turns into a paramagnetic material.
Curie temperature is the temperature at which the ferromagnetic material becomes paramagnetic material.
Comparison of materials:
Characters | Diamagnetic materials | Paramagnetic materials | Ferromagnetic materials |
Alignment | Perpendicular | Parallel | Parallel |
Movement | Stronger to the weaker part | Weaker to the stronger part | Weaker to the stronger part |
Magnetisation | Opposite to magnetic field | Along the magnetic field | Strongly magnetised |
External temperature | Does not affect the magnetic properties | Affects the magnetic properties | Affects the magnetic properties |
Example | Water, air | Oxygen, platinum | Iron, cobalt |
