William Sturgeon invented the first electromagnet in 1924. The device consisted of a piece of horse-shoe shaped iron with 18 turns of wrapped copper wire around the iron. While sturgeon invented the first electromagnet, Hans Christian Ørsted discovered the phenomenon of electrically created magnetic fields just 4 years before Sturgeon invention.
The first electromagnet was made by William Sturgeon, a British electrician, in the 1824. He got the idea from a Danish scientist, Hans Christian Oersted, who was the first to discover that an electric current produces a magnetic field. Sturgeon’s electormagnet was composed of a horseshoe shaped piece of iron with a piece of wire wrapped around it and connected to a battery. This was an important advancement for technology, as it created a magnet with a controllable magnetic field. While permanent magnets have a set magnetic field, the magnetic field of an electomagnet changes in accordance with the amount of electric current passing through it.
