• Gale suggested that his simple electro-magnet, with its few turns of thick wire, should be replaced by one with a coil of long thin wire. Rupert S. Holland. Historic Inventions.
• So far Morse had only used his recorder over a few yards of wire, his electro-magnet had been of the simplest make, and his battery was a single pair of plates. Rupert S. Holland. Historic Inventions.
• In 1840 Davenport, by means of his electric motor, printed a news sheet called the _Electro Magnet and Mechanics’ Intelligencer_. Edward W. Byrn. The Progress of Invention in the Nineteenth Century.
