उत्तर
The alloys called alnico and nipermag are used for making industrial magnets.
Explanation:
Alnico and Nipermag are special mixtures of metals used to make strong and long-lasting magnets for machines. They can hold their magnetism for a long time and are used in industries. Alnico is made from aluminium, nickel, cobalt, and iron, while Nipermag is made from nickel, iron, and titanium. These materials make the magnets stronger than ordinary iron.
