Answer:
(D) All of the above
Explanation:
Magnets are made from magnetic metals – iron, nickel and cobalt. These are the only pure metals that can be turned into a permanent magnet. Steel is an alloy of iron and so can also be made into a magnet. Alnico and Nipermag alloys are ferromagnetic, with a high coercivity (resistance to loss of magnetism) and are used to make permanent magnets.
