REASON OF PARAMAGNETIC, DIAMAGNETIC AND FERROMAGNETIC SUBSTANCES

Mention the range of magnetic susceptibility for ( a) Diamagnetic substances ( DMS) (b) Paramagnetic substances (PMS) (c ) Ferromagnetic substances (FMS).

Assertion: The ferromagnetic substance do not obey Curie's law. Reason: At Curie point a ferromagnetic substance start behaving as a paramagnetic subsrance.

Assertion: The ferromagnetic substance do not obey Curie's law. Reason: At Curie point a ferromagnetic substance start behaving as a paramagnetic subsrance.

Needles N_(1) , N_(2), and N_(3) are made of a ferromagnetic, a paramagnetic and a diamagnetic substance respectively . A magnet when brought close to them will

Assertion: the ferromagnetic substance do not obey Curie's Law. Reason : At Curie point a ferromagnetic substance start behaving as a paramgnetic substance.

Diamagnetic , Paramagnetic , and Ferromagnetic Substances

Assertion : On heating ferromagnetic or ferromagnetic substance , they become paramagnetic Reason :The electrons change their spin on heating
