Which Metals Are Magnetic? | Metal Supermarkets UK
The most common metals used for permanent magnets are iron, nickel, cobalt and some alloys of rare earth metals. There are two types of permanent magnets: those from "hard" magnetic materials and those from "soft" magnetic materials. "Hard" magnetic metals tend to stay magnetized over a long period. Common examples are:

Cobalt (Co) | AMERICAN ELEMENTS
Cobalt is often alloyed with iron, nickel and other metals to make Alnico, an alloy of unusual magnetic strength with many important uses. Samarium-cobalt, for instance, is one of the highest strength magnet alloys known.Cobalt compounds are used to produce a brilliant and permanent blue color in ceramic glazes, glass, pottery, tiles, and enamels.
Cobalt Alloys - an overview | ScienceDirect Topics
Cobalt alloys have good magnetic properties, corrosion resistance, wear resistance, and high temperature strength. These properties arise from the crystallographic nature of cobalt, the solid-solution-strengthening effects of Cr, W, and Mo, the formation of metal carbides, and the corrosion resistance imparted by Cr.
Is Nickel Magnetic? - UMD
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).
