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
Sturgeon was born Edward Hamilton Waldo in Staten Island, New York, in 1918. His name was legally changed to Theodore Sturgeon at age eleven after his mother's divorce and subsequent marriage to William Dicky ("Argyll") Sturgeon. [3] Theodore's birth father, Edward Waldo, was a color and dye manufacturer of middling success.
1825–1833 William Sturgeon: British, scientist; 1825 – invented the electro-magnet; 1833 – built first commutated rotating electric machine that was demonstrated in London. [3] 1832–33, Hippolyte Pixii: French, instrument maker, built the first AC generating apparatus out of a rotation; and, the following year, an oscillating DC generator.

[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]
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 ...
In February 1841, Sturgeon promoted James Prescott Joule's first public lecture at the Gallery and the directors were sanguine about the Gallery's prospects. However, ultimately, there proved to be insufficient local people willing to pay the admission fee and the Gallery closed in 1842. [ 1 ]

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.) The iron was varnished to insulate it from the windings. When a current was passed through the coil, the iron ...
