What is a common magnet made of?
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.
How do you create a magnet?
We make magnets by exposing ferromagnetic metals like iron and nickel to magnetic fields. Moreover, when we heat these metals to a certain temperature, they get permanently magnetized. Besides, it's also possible to temporarily magnetize them by using a variety of methods that you can try safely at home.
