The iron loss of high-speed machines increases with the increasing of the alternate frequency of magnetic field in the iron,and the accurate calculation of iron loss is more important to the high-speed machines.In this paper,the coefficients of hysteretic loss and eddy-current losses in the iron loss model are determined based on loss experiments of …

Ferromagnets. Only certain materials (e.g., iron, cobalt, nickel, and gadolinium) exhibit strong magnetic effects. These materials are called ferromagnetic, after the Latin word ferrum (iron). A group of materials made from the alloys of the rare earth elements are also used as strong and permanent magnets (neodymium is a common one).

As long as a metal has some iron in it, you can magnetize it using another magnetic metal or an electromagnet. While you need a strong magnet to make another metal magnetic, the magnetism produce will probably not be very strong; it will be sufficient to pick up a paperclip or a screw. The strength of the magnet depends upon the iron …

In order to demagnetise permanent magnets, a magnetic field with very high field strength is required, as magnets are made of magnetic materials that have a much higher coercive force (wikipedia/coercive field strength) than iron or steel. After they are manufactured and processed, magnets are magnetised using a very strong magnetic field to up ...

As iron core of the armature is rotating in magnetic field, some losses occurs in the core which is called core losses.Normally, machines are operated with constant speed, so these losses are almost constant. These losses are categorized in two form; Hysteresis loss and Eddy current loss. Hysteresis Loss in DC Machine
