A spherical transformer and process for forming same is set forth. Hollow, hemispherical elements are rotated to enable a cooperating cutting tool to impart a helical impression therein. An adhesive is sprayed into the interiors of both hemispheres and thereafter powdered metal, such as stainless steel, is directed thereon to form a sheet-like core that when both hemispheres are joined to provide an uninterrupted metal core with said hemisphere. A primary winding is inserted into the aforenoted grooves about one hemisphere and a secondary winding is positioned into the helically cut grooves in said second hemisphere. The thusly formed transformer is positioned on a base for a stability thereof.
