- ADiamagnetic, Paramagnetic, Ferromagnetic
- BParamagnetic, Diamagnetic, Ferromagnetic
- CDiamagnetic, Ferromagnetic, Paramagnetic
- DFerromagnetic, Paramagnetic, Diamagnetic
Correct answer
A. Diamagnetic, Paramagnetic, Ferromagnetic
Step-by-step solution
Material has a small negative susceptibility that is independent of temperature. This is the characteristic property of diamagnetic materials.
Material has a small positive susceptibility that follows Curie's law (). This is characteristic of paramagnetic materials.
Material has a very large positive susceptibility, which is a property of ferromagnetic materials. Above the Curie temperature, a ferromagnetic material transitions into a paramagnetic material (like material ).
Therefore, the correct sequence is Diamagnetic, Paramagnetic, Ferromagnetic.
