Alloy Magnet: Alloy metals, for example, prepared by the mixture of iron, nickel, cobalt, copper, and aluminium is used for making a permanent magnet. These are called alloy magnet. If there exists more than 0.8 parts or 80% carbon in an iron alloy, then that produces a permanent magnet.
A magnetic alloy is a mixture of a variety of metals from the periodic table that contains at least one of the three main magnetic elements: iron (Fe), nickel (Ni), and cobalt (Co). Diversity exists between the varieties of magnetic alloy resources and grades. Such an alloy necessity contains but is not limited to one or more of these metals. Magnetic alloys have become familiar, particularly in the form of steel (iron and carbon), alnico (iron, nickel, cobalt, and aluminum), and permalloy (iron and nickel). The strongest magnetic element is iron, which allows items made out of these alloys to attract magnets. They are generally used in industrial and used electronics. For example, in large electric motors, microphones, loudspeakers, electric guitar pickups and microwaves.
