Need To Know About Magnet Types

When you think of magnet you might think about the one that stuck to your refrigerator right now. Or maybe you think of their red giant U-shaped magnet from the old cartoon. This is the second permanent strong magnetic strips but there are more types of magnets then just that and this article will define them all.

Permanent magnets are permanent magnets. It is that you cannot turn them on or off. Permanent magnets are made of ferromagnetic material. Ferromagnetic materials are materials that molecules and atoms all have magnetic fields that are positioned to reinforce one another.

 Permanent magnets can then be classified into four smaller groups. This is a Neodymium Iron Boron 1. 2. 3. Alnico 4. Samarium Cobalt ceramics or ferrite.

The first two types are the strongest and very difficult to de-interest. But they are also the rarest because they come from a rare material in the soil. The third class of Alnico magnets is the most affected by the temperature, but it is the easiest to de-interest.

That is why they are used most often outside like a horseshoe. The last type is the most commonly used today they are a bit like the opposite of where they are strong Alnico but are strongly influenced by temperature.

They can also be divided further into two other categories of injection molded and flexible magnets. Injection-molded magnet made in part with the powder and they are created by a process that includes injecting and molding them more powerful but inflexible. Flexible magnets are made in the strip and are much more flexible but less powerful.
