Assertion (A): Ferromagnetic substances do not obey the simple form of Curie’s L

1. Assertion (A): Ferromagnetic substances do not obey the simple form of Curie’s Law. Reason (R): At the Curie point, a ferromagnetic substance begins behaving as a paramagnetic substance. Which is correct?

 

Ferromagnetic substances genuinely follow the more complex Curie-Weiss law rather than simple Curie’s Law. Reason R is also true, but describes behaviour specifically above the Curie point, not a full explanation of A.
