“…Such components are with compact volume but also required cores possessing proper geometric shape universality and excellent magnetic properties. Due to these facts powdered and compacted magnetic cores applicability with Fe-Ni [1], Fe-Co [2,3,4] and Fe-based [5] are under very intensive research nowadays. A magnetic powder core (MPC) is a distributed-air-gap core with an arbitrary construction-for example, toroidal, race-track, block, etc.…”
