Best Answer

An electromagnet can be any size from a few millimetres (magnetic tape or computer hard disc read/write heads) to several metres (industrial uses such as scrap yards for lifting steel, or research such as parts in particle accelerators and fusion reactors). The only limit to the upper size would be available materials and manufacturing technology.
