Question

why do ferrimagnetic substances possess small net magnetic moments in spite of the presence of large number of unpaired electrons?​

Answer 1

Explanation:

Ferromagnetic AntifcrromagneticFerrimagnetic (iv) Antiferromagnetism. Certain paramagnetic substances allign themagnetic moments due to theunpaired electrons under the influence of external magnetic field in such a way that they mutually cancel. As a result, they possess zero or nomagnetic moment.

Answer 2

Answer:

This property is due to the presence of unpaired electrons. e.g., Cu2+, O2. Certain paramagnetic substances allign the magnetic moments due to the unpaired electrons under the influence of external magnetic field in such a way that they mutually cancel. As a result, they possess zero or no magnetic moment.
