Q: What causes iron, nickel, and cobalt to be attracted to ...

However, sometimes (in iron, nickel, and cobalt for example) you’ll have one or more un-paired electrons. The magnetic fields of these electrons aren’t canceled out by another, oppositely-oriented, electron. As such they lend an overall magnetic field to the atom they inhabit.

Is Nickel Magnetic? - University Of Maryland

Is Nickel Magnetic? The element Nickel (Ni) is one of the few ferromagnetic metals. Ferromagnetic means they are attracted to magnets and can be magnetized themselves. Most metals aren’t magnetic with the exception of iron, nickel, cobalt, gadolinium, neodymium and samarium. Because Nickel (Ni) is ferromagnetic it is used in making Alnico magnets (consisting of aluminium, nickel, and cobalt ...

Magnetic alloy - Wikipedia

A magnetic alloy is a combination of various metals from the periodic table such as ferrite that contains at least one of the three main magnetic elements: iron (Fe), nickel (Ni), or cobalt (Co) etc.. Such an alloy must contain but is not limited to one or more of these metals. Magnetic alloys have become common, especially 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 t…
