Demagnetizasiýa egrileri

Demagnetizasiýa egrisi ýa-da BH egrisi, gaty ýer magnitlerini goşmak bilen gaty magnit materiallary üçin histereziň ikinji kwadrantydyr. Magnitiň magnit aýratynlyklary, şol sanda magnit meýdanynyň güýji we demagnetizasiýa garşylygy barada maglumat berýär. Esasanam ýokary temperaturadaky egrilik inersenerlere iş talaplaryna laýyk gelýän magnit materialyny we derejesini hasaplamak we tapmak üçin möhüm salgylanma berýär. Şonuň üçin, her bir synpdan öň süzülen Neodim magnitleri we Samarium Kobalt magnitleri üçin birnäçe ýokary iş temperaturasynda demagnetizasiýa egrilerini taýýarlaýarys. Demagnetizasiýa egrileri üçin her öýjüge degişlilikde basyň.
