Answer» Solution : 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 placedin a magnetic field, all the domings get oriented in the direaction of magneticfield and a strong magnetic field is produced . This ording of domains presists even when the external magnetic fieldsi removed. Hence, the ferromagnetic substance becomes a permanment magnet.
