REASON OF PARAMAGNETIC, DIAMAGNETIC AND FERROMAGNETIC SUBSTANCES

NO is paramagnetic, while NO^(oplus) is diamagnetic.

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

Give reason for the statement [Ni(CN)_(4)]^(2-) is diamagnetic while [NiCl_(4)]^(2-) is paramagnetic in nature .

An example of diamagnetic substance is
