Assertion : The ferromagnetic substance do not obey Curie’s law.
Reason : At Curie point a ferromagnetic substance start behaving as a paramagnetic substance.
The correct answer to this question is option 'B', which states that both the Assertion and Reason are correct, but the Reason is not a correct explanation of the Assertion. Let's understand why this is the correct answer.
Explanation:
1. Understanding Curie's Law:
Curie's Law states that the magnetic susceptibility of a paramagnetic substance is inversely proportional to the absolute temperature. In other words, as the temperature increases, the magnetic susceptibility decreases. This law is valid for paramagnetic substances but not for ferromagnetic substances.
2. Assertion: The ferromagnetic substance do not obey Curie’s law.
The assertion is correct. Ferromagnetic substances do not follow Curie's Law. The magnetization of a ferromagnetic substance does not depend solely on temperature, as it does in paramagnetic substances.
3. Reason: At Curie point a ferromagnetic substance starts behaving as a paramagnetic substance.
The reason given is partially correct, but it does not provide a correct explanation for the assertion. The Curie point is the temperature at which a ferromagnetic substance loses its ferromagnetic properties and becomes paramagnetic. However, this does not mean that a ferromagnetic substance starts behaving as a paramagnetic substance at the Curie point.
4. Explanation:
Ferromagnetic substances exhibit strong permanent magnetization even in the absence of an external magnetic field. They have a characteristic property called hysteresis, which means that their magnetization depends not only on temperature but also on the history of the material. This hysteresis behavior is not accounted for by Curie's Law.
At temperatures below the Curie point, ferromagnetic substances have a spontaneous magnetization even in the absence of an external field. As the temperature increases towards the Curie point, the spontaneous magnetization decreases, and at the Curie point, it disappears completely. Above the Curie point, the substance becomes paramagnetic, which means that its magnetic properties are dominated by the influence of an external magnetic field.
Conclusion:
In conclusion, the assertion is correct that ferromagnetic substances do not obey Curie's Law. The reason provided is partially correct in stating that at the Curie point, a ferromagnetic substance loses its ferromagnetic properties and becomes paramagnetic. However, it does not provide a correct explanation for why ferromagnetic substances do not follow Curie's Law. Therefore, the correct answer is option 'B'.
