Norman P. Goss was an inventor and researcher from Cleveland, Ohio
, USA.
He graduated from Case Institute of Technology in 1925. He made significant contributions to the field of metals research, and in 1935 he published a paper and patented a method to obtain so-called grain-oriented electrical steel, which has highly anisotropic
magnetic properties. This special "grain-oriented" structure was named after its inventor and it is referred to as the "GOSS structure".
Grain-oriented electrical steel enabled the development of highly efficient electrical machines
, especially transformer
s. Today, the magnetic core
s of all high-voltage high-power transformers are made of grain-oriented electrical steel.
Ohio
Ohio is a Midwestern state in the United States. The 34th largest state by area in the U.S.,it is the 7th‑most populous with over 11.5 million residents, containing several major American cities and seven metropolitan areas with populations of 500,000 or more.The state's capital is Columbus...

Anisotropy
Anisotropy is the property of being directionally dependent, as opposed to isotropy, which implies identical properties in all directions. It can be defined as a difference, when measured along different axes, in a material's physical or mechanical properties An example of anisotropy is the light...

Electric machine
The academic study of electric machines is the universal study of electric motors and electric generators. By the classic definition, electric machine is synonymous with electric motor or electric generator, all of which are electro-mechanical energy converters: converting electricity to mechanical...
, especially transformer
Transformer
A transformer is a device that transfers electrical energy from one circuit to another through inductively coupled conductors—the transformer's coils. A varying current in the first or primary winding creates a varying magnetic flux in the transformer's core and thus a varying magnetic field...
s. Today, the magnetic core
Magnetic core
A magnetic core is a piece of magnetic material with a high permeability used to confine and guide magnetic fields in electrical, electromechanical and magnetic devices such as electromagnets, transformers, electric motors, inductors and magnetic assemblies. It is made of ferromagnetic metal such...
