This chapter presents some of the significant structural and magnetic properties of electrical steels for rotating machines. Iron and steel can be induced to show a range of magnetic effects. Hard steel once magnetised tends to remain so. Soft iron is easily magnetised but its magnetised state disappears when the field inducing it is removed.
