To understand how induction telegraphy works, were going to need to understand three areas involving electricity and magnetism: (1) electromagnetic induction; (2) coupled inductors; and (3) electrical telegraphs. [12] At times, he would refer to himself as an immigrant from Australia,[13] in the belief that he would be given more respect if people thought he was from a foreign country, as opposed to being an African American. In similar, and reverse fashion, the trains transmitter system may also send signals to the stations receiver system, all without a direct telegraphic or telephonic connection between the train and the station.
