The electromagnetic telegraph operates on a very straightforward and elegant principle. The transmitter opens and closes an electric circuit at one point. The receiver uses the electric current at any other point in the closed circuit to establish a magnetic field, the forces arising from which cause some observable mechanical effect.

Electromagnetic Devices and Inventions: The discovery of electromagnetism led to a large number of inventions and devices. Being able to turn magnetism on and off, the great strength of electromagnets, and being able to vary the magnetism by varying the electrical current are characteristics of electromagnetism used in many inventions.
The history of magnets is shrouded in mystery and legend. Ancient History. The most popular account for the discovery of magnets is a legend of a shepherd named Magnes who lived in Magnesia near Mount Ida in Greece Mount Ida was referred to as the "Mountain of the Goddess".
The Barkhausen effect makes the concept of magnetic domains audible (if not exactly music to the ear). Barlow''s Wheel English mathematician Peter Barlow devised an instrument in 1822 that built on advances from earlier in the century (including the invention the battery) to
In 1836, John Daniell (17901845) proposed an improved electric cell that supplied an even current during continuous operation. The Daniell cell gave new impetus to electric research and found many commercial appliions. In 1837 Daniell was presented the highest award of the Royal Society, the Copley Medal, for the invention of the Daniell cell.
