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
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 ...

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.)
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 ...
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.
