Book Free DemoThe 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:
- 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.
Example:
Water, air, and hydrogen are diamagnetic in nature. Some other diamagnetic materials are also listed below in the table.
