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 content.

Interior PM (IPM) machines can have severe local magnetic saturation especially in the rotor iron region above the PMs and the stator tooth-tips. In this paper, the influence of local magnetic saturation on the iron losses is comprehensively investigated in IPM machines accounting for the influence of the slot/pole number combinations. Due to local magnetic saturation, the tooth …

Hybrid-excited machines utilize the synergies of permanent magnet (PM) and wound field machines. Flux-switching PM machines have emerged as an attractive machine type due to the fact that the excitation sources are located in the stator allowing a simple robust rotor whilst providing high torque density. This paper proposes topologies of hybrid-excited flux …
