William Sturgeon (/ ˈ s t ɜːr dʒ ə n /; 22 May 1783 – 4 December 1850) was an English electrical engineer and inventor who made the first electromagnet and the first practical electric motor. Early life
A model of Wheatstone and Cooke's electric telegraph; [1] Electromagnets; [1] A ball and socket valve from Sharp, Roberts and Company; [1] Surface plates from Whitworth & Co.; [1] A "spectacular" electrotype engraving by Sturgeon of Richard I leaving Cyprus.

1823: Electromagnet invented by William Sturgeon (1783–1850). [123] 1831: Discovery that electric current could be generated by altering magnetic fields (the principle underlying modern power generation) by Michael Faraday (1791–1867). [56] 1845: Proposition that light and electromagnetism are related by Michael Faraday (1791–1867). [56]
British scientist William Sturgeon invented the electromagnet in 1824. [3] [4] His first electromagnet was a horseshoe-shaped piece of iron that was wrapped with about 18 turns of bare copper wire. (Insulated wire did not then exist.)
This made a practical electric telegraph possible. He was the first to coil insulated wire tightly around an iron core in order to make an extremely powerful electromagnet, improving on William Sturgeon's design, which used loosely coiled, uninsulated wire. He also discovered the property of self inductance independently of Michael Faraday.
William Sturgeon invented the electromagnet in 1825. [19] Electromagnets were then used in the first practical engineering application of electricity by William Fothergill Cooke and Charles Wheatstone who co-developed a telegraph system that used a number of needles on a board which were moved to point to letters of the alphabet. A five needle ...
But in 1914 when D. D. Sturgeon-founder of Sturgeon Electric-wanted to give his ill son some Christmas joy, he wrapped his pine trees with electric bulbs, which were dipped in red and green paint.
English physicist William Sturgeon developed the first electromagnet. 1827: German physicist Georg Ohm introduced the concept of electrical resistance. 1831: English physicist Michael Faraday published the law of induction (Joseph Henry developed the same law independently). 1831
