A magnetic core is a piece of magnetic material with a high magnetic permeability used to confine and guide magnetic fields in electrical electromechanical and magnetic devices such as electromagnets transformers electric motors generators inductors magnetic recording heads and magnetic assemblies it is made of ferromagnetic metal such as iron or ferrimagnetic compounds such as ferrites.
Laminated iron sheets are used to minimize.
If a solid core were used in a power transformer the losses would be very high and the temperature would be excessive.
For this reason cores are laminated from very thin sheets such as 0 23 mm and 0 28 mm to reduce the thickness of the individual sheets of steel normal to the flux and thereby reducing the losses.
Once upon a time laminating a card or a document had to be done professionally.
But they can be a little pricey.
