British electrical engineer William Sturgeon, a former soldier who began to dabble in the sciences at the age 37, invented the electromagnet in 1825. Sturgeon’s device came a mere five years after a Danish scientist discovered that electricity emitted magnetic waves. Sturgeon harnessed this idea and conclusively demonstrated that the stronger the electric current, the stronger the magnetic force.
Electromagnet invented 1825 by William Sturgeon In 1825, Lancastrian electrician, William Sturgeon, revealed his invention of the electromagnet. This enabled electrical energy to be used in the design of controllable machinery.
William Sturgeon, (born May 22, 1783, Whittington, Lancashire, Eng.—died Dec. 4, 1850, Prestwich, Lancashire), English electrical engineer who devised the first electromagnet capable of supporting more than its own weight. This device led to the invention of the telegraph, the electric motor, and numerous other devices basic to modern technology.
Invented by : William Sturgeon Invented in year : 1825. Electromagnetic is a temporary magnet which is made by coiling wire around an iron core; when current flows in the coil the iron becomes a magnet. When the current doesn’t flow the magnetic effect ceases.
William Sturgeon was an English electrical engineer. In 1825 he built the first practical electromagnet, in 1832 invented the commutator for electric motors and in 1836 made the first moving-coil galvanometer and carried out research into atmospheric charge. His Annals of Electricity (1836) was the first journal of its kind in Britain.
William Sturgeon, English inventor, c 1830-1840. UNITED KINGDOM – AUGUST 27: Engraving of William Sturgeon (1783-1850) who produced an improved electromagnet in 1821. This had a soft iron bar that was coated with shellac varnish to provide a more concentrated magnetic field.
Born May 22, 1783, in Whittington, near Lancaster; died Dec. 4, 1850, in Prestwich, near Manchester. British inventor in the field of electrical engineering. Sturgeon received no specialized education. He invented the soft-iron electromagnet in 1825. In 1830 he developed a process for producing amalgamated zinc plates for galvanic cells.
In 1825 William Sturgeon developed the first practical electromagnet by loosely winding a coil of un-insulated wire around a horseshoe-shaped piece of iron. To prevent the wire from shorting Sturgeon coated the iron in varnish. The seven-ounce magnet was able to support nine pounds of iron using the current from a single cell.
William Sturgeon invented the electromagnet in 1824 – but died penniless and virtually unknown in Prestwich.
