Actually it is more general than that.
During an electrophoresis macromolecules are separated within a gel with the help of an electrical field.
You can isolate/retrieve these molecules by applying another electrical field so that you force the molecules of interest to move out from the gel and into solution.(I won't get into technical details). You can use it not only for DNA but for any type of macromolecule that you analyze by electrophoresis like proteins (I've used it to retrieve an enzyme).

Electroelution is a method used to extract a DNA sample from an electrophoresis gel by applying a current in the plane of the smallest dimension of the gel, drawing the DNA to the surface for extraction.
