What type of substances would make better permanent magnets, ferromagnetic or ferrimagnetic? Justify your answer.

Explanation

ferromagnetic substances make better permanent magents. This is because the metal ions of a ferromagnetic substance are grouped into small regions called 'dmains'. Each domain acts as a tiny magnet. These domains are randomly oriented. when the substance is placed in a magnetic field, all the domings get oriented in the direaction of magnetic field and a strong magnetic field is produced . This ording of domains presists even when the external magnetic field si removed. Hence, the ferromagnetic substance becomes a permanment magnet.
