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
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.
A portative electromagnet is one designed to just hold material in place; an example is a lifting magnet. A tractive electromagnet applies a force and moves something. [8] Electromagnets are very widely used in electric and electromechanical devices, including: Motors and generators; Transformers; Relays; Electric bells and buzzers ...
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]
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
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.
He was the first to coil insulated wire tightly around an iron core in order to make a more powerful electromagnet, improving on William Sturgeon's electromagnet which used loosely coiled uninsulated wire. Using this technique, he built the strongest electromagnet at the time, for Yale.
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.
