    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.
