rare earth metals, building an electromagnet, best bet: Hi, Most simple electromagnets use an iron conductor (such as a nail) and I think that will be your best bet. There are other conductors that can be used, but they are usually rare earth metals and therefore difficult/expensive to obtain. ... About Michael Spurr; ... • U.S.
