Electromagnetic Communication

For most of us, if you asked, one of the hardest inventions to be without would be our telephones; whether land-line, mobile or even smartphone, they all rely on electromagnetic communication. From the first practical application of electricity - the telegraph, to the entire computer age, we are looking at developments largely using the same fundamental technology. We will focus on pre-transistor developments, starting with the principles of electricity and electromagnets, and working our way to telephones with a brief nod to television and computers.
