cobalt magnetism

What do you know about cobalt? Cobalt is a shiny bluish metal. They're also some very special type of metal: Almost everything of significance is made of it, including magnets! When you think of magnets, you think of the magnets that stick on your refrigerator, am I right? Those magnets are pretty fun and are good for holding up some pictures or notes. However, did you know that magnets play a central role in many others of the things we use in our everyday lives? They make our technology run smoother!

Cobalt is unique in that it is intrinsically magnetic. This means that cobalt can magnetically pull other metal on its own. It will adhere to items made of iron or nickel, for instance, without any added assistance. Isn't that cool? How can that be, you ask. Well, it's like magic but it's really science!

The Secret of Cobalt's Magnetism Uncovered

Atoms are little particles so small we can not see them with our eyes. They comprise the fundamental structure of everything, from metals such as cobalt. If we had a powerful microscope and studied cobalt, we would notice that its atoms are arranged in a structure known as a crystal lattice. That special arrangement produces an electric field around the cobalt—even though cobalt is not magnetic in itself, this electric field is what makes it magnetic.

For this reason cobalt is magnetic and thus incredibly useful with applications in many critical areas. And cobalt is primarily used to make permanent magnets. These magnets retain their magnetism for a long time and are found in various household objects; however, they are also more commonly found in the parts of motors, generators and speakers, which we use to listen to music. Smart devices would be much worse without cobalt magnets!
