Magnets are materials or devices that attract items containing the elements cobalt, magnetic fieldnickelelectromagnetmagnetitemagnetic fieldSelect your answer, and iron. About 2000 years ago, some people found rocks called magnetitemagnetic fieldelectromagnetnickelmagnetic fieldSelect your answer that attracted iron. Each particle that makes up a magnet has its own magnetic fieldelectromagnetmagnetiteelectric currentSelect your answer. When all these particles line up in the same magnetic fieldelectromagnetdirectionmagnetic fieldelectric currentSelect your answer, their magnetic fields act together. Magnets can also be created using a(n) magnetic fieldelectric currentmagnetiteelectromagnetSelect your answer. When current runs through a wire, a(n) electromagnetmagnetic fieldelectric currentmagnetiteSelect your answer forms. A temporary magnet called a(n) magnetic fieldmagnetiteelectromagnetmagnetic fieldelectric currentSelect your answer can also be created by current flowing through wire wrapped around an iron bar.
