Radio development began as "wireless telegraphy." During the early development of wireless technology, and continuing long after its widespread adoption, disputes persisted as to who could claim credit for the invention of radio. The matter was important for economic, political and nationalistic reasons. Various scientists proposed that electricity and magnetism were linked. In 1802 Gian Domenico Romagnosi suggested the relationship between electric current and magnetism but his reports went unnoticed. In 1820 Hans Christian Orsted performed a simple and today widely known experiment on man-made electric current and magnetism. He demonstrated that a wire carrying a current could deflect a magnetized compass needle. Orsted's work influenced Andre-Marie Ampere to produce a theory of electromagnetism. Several different electrical, magnetic or electromagnetic physical phenomena can be used to...
