Re: Who discovered and/or invented electromagnets?

It is hard to narrow this down to one person, as many people did work in 
this area simultaneously.  Oersted published the first paper detailing the 
effects which led to further work in electromagnetism.  Ampere followed 
this with a mathematical formula.  Faraday did a great deal of work on the 
subject.  Probably Joseph Henry invented what we think of as an 
electromagnet today.
