Magnetism

Explain how objects like the earth and metals can be permanent or temporary magnets.

When it comes to magnets, a domain is a cluster of atoms that are magnetically aligned. A permanent magnet has domains that are all lined up in the same way. The three most common magnets are iron, nickel, and cobolt. Some objects have magnetic material and the potential to become magetic, however, are not always magnetic. They have domains, but they are not always lined up. Other objects are made of non-magnetic material. They have domains but these domains can never be lined up. In these types of objects, there are magnetic fields but no magnetic domains. In conclusion, all objects have domains. If these domains are lined up, the object is magnetic or has potential to become magnetic. If the domains are not lined up, the object cannot become magnetic.
