we are here going to discuss our asked question what type of substances would make better permanent magnets, ferromagnetic or ferrimagnetic justify ?
Key points to answer this question : you have to remember that the Ferromagnetic substances are strongly and also permanently magnetised it means the Ferromagnetic substances magnetised once then contain magnetic characteristics remains for a long time whereas ferrimagnetic substances are weakly (temporarily) magnetised means once ferrimagnetic substance magnetised once then they does not contain magnetic characteristics for a long time.
Solution : Ferromagnetic substances are those substance which make better permanent magnets than ferrimagnetic substances. means Ferromagnetic substances are better permanent magnets as compare to ferrimagnetic substances. and the cause of this property is that The metal ions of a ferromagnetic substance are grouped into small regions which are called as domains and these are randomly oriented in nature. When a magnetic field is applied to ferromagnetic substance, all domains are oriented in the direction of the magnetic field and because of this domains orientation in the direction of the magnetic field Now the ferromagnetic substance behaves as a magnet. also you have to keep remember that When the applied magnetic field is removed from this substances , the magnetic character is retained bye the substance. hence, the ferromagnetic substance becomes a permanent magnet. means after removing the applied external magnetic field the substance remains the property of magnet that is why ferromagnetic substance is called permanent substances as compare to ferrimagnetic substances.
The property of being permanently magnetized from the external applied magnetic field is not found in ferrimagnetic substances because they lose the property when external magnetic field is removed or They lose their magnetic property on heating up.
Thus Ferromagnetic substances are better permanent magnets as compare to ferrimagnetic substances.
