William Sturgeon (/ ˈ s t ɜːr dʒ ə n /; 22 May 1783 – 4 December 1850) was an English physicist and inventor who made the first electromagnet and the first practical electric motor. Early life [ edit ]
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 ...
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
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.
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 ...
Ms Sturgeon joined the SNP at just 16 and first stood for election in the 1992 general election, as the SNP’s candidate in Glasgow’s Shettleston. The youngest parliamentary candidate in ...
The SNP power couple's marriage ending and a plea for North Sea fossil fuel support make the papers.
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]
