The Development of Wireless Communication Leading to the Alexanderson Alternator Not much has changed in human nature in the past couple centuries. When we want something, we desire exactly what we want without deviation and we wish to have it quickly. This is as evident in modern times as it was in the late nineteenth and early twentieth centuries. It is difficult to imagine for the modern man, but there was once a time when messages and information had to be delivered by hand, horseback or by vehicle. This was a very big problem in a world that was expanding and evolving rapidly and was full of growing local and international turmoil. The more the world began to expand, the harder it became to relay messages and information, and the…show more content…
Orsted was dumbfounded about his discovery, but had no way of explaining how it was possible that the electrical current had an effect on the magnetic needle of the compass. After reading about Orsted’s results, a man by the name of André-Marie Ampère sought to find the reason for this occurrence and what he discovered changed the field of electrical engineering forever. “He demonstrated that when two wires were placed parallel to one another, both carrying an electric current, they'd either be attracted to or repulsed by each other depending on which directions the currents were traveling.” [4]. Ampere later created what is known as Ampere’s Law which relates electricity and magnetism. So why was this relationship between electricity and magnetism so important to the field of electrical information transmission? This question began to be answered by a man named Joseph Henry in 1830. Intrigued by the recent innovation of electromagnetism, Henry decided to test its effectiveness in the field of electrical transmission. Henry decided that if he passed current through one end of a transmission wire he could use the current to activate an electromagnet at its opposite end. Henry attached a bell to the electromagnet a mile from his current emission point and was able to ring the bell by sending current through the line. [2] This telegraph system was brilliant, but Samuel Morse saw even more potential in the model.
