The magnet was made of 18 turns of bare copper wire (insulated wire had not yet been invented). [1] 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.
These experiments culminated in William Sturgeon wrapping wire around a horseshoe-shaped piece of iron and running electric current through the wires creating the first horseshoe magnet. [ 3 ] This was also the first practical electromagnet and the first magnet that could lift more mass than the magnet itself when the seven-ounce magnet was ...
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 ...
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.
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
A magnet is a material or object that produces a magnetic field. ... This led William Sturgeon to develop an iron-cored electromagnet in 1824. [7]
In 1825, William Sturgeon invented the electromagnet, with a single winding of uninsulated wire on a piece of varnished iron, which increased the magnetic force produced by electric current. Joseph Henry improved it in 1828 by placing several windings of insulated wire around the bar, creating a much more powerful electromagnet which could ...
William Aspdin obtains a patent for Portland cement (concrete). 1825. William Sturgeon invents the electromagnet. 1828. A mechanical reaping machine is invented by Patrick Bell. [30] 1831. Electromagnetic induction, the operating principle of transformers and nearly all modern electric generators, is discovered by Michael Faraday. 1835
