An electromagnet is by far the most important electrical structure that exists in almost all electronic devices. Most of today's Radios, televisions, door bells, telephones, telegraphs and computers could not exist without electromagnets.                                                                               

In an electromagnet project, you may make some of the simple devices that use electromagnet; however the most important electromagnet projects study the strength of electromagnet. There is an electromagnet kit available at MiniScience.com; however, many students may just purchase the magnet wire (27 AWG) and find other material (nail, battery,..) at home.
