Assertion and Reasoning

Assertion: The ferromagnetic substance do not obey Curie’s law.
Reason: At Curie point a ferromagnetic substance starts behaving as a paramagnetic substance.

Explanation:
Ferromagnetic substances are those substances that are strongly magnetized in the presence of an external magnetic field. They exhibit spontaneous magnetization and have a large positive magnetic susceptibility. However, ferromagnetic substances do not obey Curie’s law.

Curie’s law states that the magnetization of a substance is directly proportional to the magnetic field applied to it at a fixed temperature. It applies to diamagnetic and paramagnetic substances. But, ferromagnetic substances do not obey this law. Ferromagnetic substances exhibit hysteresis, which is a phenomenon where the magnetic behavior of the substance depends on the history of the magnetic field applied to it.

At Curie point, a ferromagnetic substance starts behaving as a paramagnetic substance. Curie point is the temperature at which a ferromagnetic substance loses its ferromagnetic properties and becomes paramagnetic. Above the Curie point, the substance does not exhibit spontaneous magnetization and its magnetic susceptibility decreases rapidly.

Therefore, the Assertion is correct, but the Reason is incorrect. At Curie point, a ferromagnetic substance does not start behaving as a paramagnetic substance, but it loses its ferromagnetic properties and becomes paramagnetic. The Reason does not provide a correct explanation for the Assertion.

Conclusion:
Ferromagnetic substances do not obey Curie’s law, and at Curie point, they lose their ferromagnetic properties and become paramagnetic. The Assertion is correct, but the Reason is incorrect.

The susceptibility of ferromagnetic substance decreases with the rise of temperature in a complicated manner. After Curie point in the susceptibility of ferromagnetic substance varies inversely with its absolute temperature. Ferromagnetic substance obey's Curie's law only above its Curie point.
