How many of the following compounds show ferrimagnetism? \[ \mathrm{Fe}_3 \mathrm{O}_4 ; \mathrm{MgFe}_2 \mathrm{O}_4 ; \mathrm{NiFe}_2 \mathrm{O}_4 ; \mathrm{MnO} ; \mathrm{CrO}_2 \]
- A 1
- B 2
- C 3
- D 4
Answer & Solution
Correct Answer
(C) 3
Step-by-step Solution
Detailed explanation
In ferrimagnetic substances, the magnetic moments of the domains are alligned in parallel and antiparallel directions in unequal number. The net magnetic moment is small. Thus, these are weakly attracted by magnetic field than ferromagnetic substances and these also lose…
