Answer / gautham sharma
We use laminated metalic plates to make the cores of transformers and electric motos and many other things. This is to avoid energy loss in the form of Eddy Current. Eddy current are circular loops of current which form conductind plates or surfaces which can result energy loss in the form of heat. Laminated cores increase the resistance by a substantial amount and reduces eddy current.
