text_original: But the electromagnet supplies a more powerful magnetic field than the strongest permanent magnet; therefore in all the dynamos of to  day, electromagnets are employed. In the very largest dynamos there are a number of these, each more powerful than the strongest one made by Henry. A MODERN DVNAUO The armature in Faraday's dynamo was merely a copper disk. Present day armatures are made up of a core or inner portion, and the windings of copper wire over the core.
