Well...when you wrap a wire around a battery, an electric current begins to flow....when the wire is then wrapped around an iron core material such as a nail...the nail will then become magnetized...As long as the wire is wrapped around the nail and then connected to the positive and negative terminals of a battery, this will create an electromagnet..
