Question

Alloys like alnico and nipermag are used in industry

Answer 1

alnico is an alloy of aluminum iron nickel.and cobalt used to make permanent magnents.
use of permanent magnet im industry :--
1. Lift heavy iron object
2. Sperate metallic object
3. Extract metals from ores

Nipermag is an alloy of iron that containing nickel, aluminium and titanium. Alloys like Nipermag and Alnico are very hard and are often used in the production of industrial scale magnets. Some uses of these magnets may be in loudspeakers, microphones, ammeters and voltmeters, etc…

Answer 2

Answer:

Both these alloys are used for making permanent magnets, which are used in sensors, microphones, loudspeakers, clocks etc. The permanent magnets made from these alloys are much stronger than the magnets made from steel.
