Full Answer

The rotating magnetic field is the backbone of alternating current machinery in modern day. Tesla developed and patented his alternating current electrical system, which successfully competed with Thomas Edison's system, and later sold it to George Westinghouse. Tesla's power system is still used worldwide today. He also invented the Tesla coil in 1891, an apparatus that uses capacitors and inductors to produce alternating currents and led to many new developments in radio technology. Tesla planned a hydroelectric plant for Niagara Falls and attempted to build a large information sharing system with an electrical tower, but financial issues kept him from success.

  • Q:

    What year was the first radio invented?

    A:

    The precursor to the radio, the Tesla coil, was invented by Nikola Tesla in 1884, and Tesla's device to send a radio signal, which was ready to go, was burned up in a lab fire in 1895. Instead, Guglielmo Marconi tested his wireless signal device in 1896; many say he relied on Tesla's technology to create it.
