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
1825 – William Sturgeon, founder of the first English Electric Journal, Annals of Electricity, found that an iron core inside a helical coil of wire connected to a battery greatly increased the resulting magnetic field, thus making possible the more powerful electromagnets utilizing a ferromagnetic core. Sturgeon also bent the iron core into ...

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.)
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]
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.
In 1825 William Sturgeon of Woolwich, England, invented the horseshoe and straight bar electromagnet, receiving therefor the silver medal of the Society of Arts. [71] In 1837 Carl Friedrich Gauss and Weber (both noted workers of this period) jointly invented a reflecting galvanometer for telegraph purposes.
