The core is made of high magnetic permeability grain-oriented electrical sheet, with with a 45 degree cut and intercalated step lap joints method. Alternatively, it could be of amorphous type, and which is a crystalline structure that guarantees extremely low losses, up to 4 times lower compared to the standard grain oriented solution.
