The basic arrangement is ess entiall y the same and has s een li tt le signi f icant change in recent years, so so me of the variations can be discussed in this article. Core The core, which provides the magnetic path to channel the flux, consists of thin strips of high-grade steel, called laminations, which are electrically separated by a thin coating of insulating material. T he st rips can be st acked o r wound, wi th the windi ngs either built integrall y around t he core o r buil t separately and assembl ed around the core sect ions. Core st eel can be hotor cold-rolled, grain-orientedo r non-grain oriented,and even laser-scribed f oradditional perf ormanc e. T hickness ranges f rom 0.23 mmto upwards of 0.36 mm. The core cross section can be circular or rectangular,
