The materials are classified based on their behaviour in a magnetic field as:
- Diamagnetic materials
- Paramagnetic materials
- Ferromagnetic materials
The characteristics of these materials are as follows.
- Diamagnetic materials can align themselves perpendicular to the magnetic field's direction when suspended in an external uniform magnetic field.
- They migrate away from the stronger part and move toward the weaker part when suspended in a non-uniform magnetic field.
- They are magnetised in the opposite direction of the magnetic field.
- The external temperature does not affect the magnetic properties of these substances.
Water, air, and hydrogen are diamagnetic in nature. Some other diamagnetic materials are also listed below in the table.
