Wahi a ka hoʻolaha kūhelu ma Dekemaba 17, 2021, ua hoʻokumu ke Komisina ʻEulopa i kahi…
Ke kila uila i kuhikuhi ʻole ʻiaʻO ka maʻamau he 2%-3.5% silicon. Loaʻa iā ia nā waiwai magnetic like ma nā ʻaoʻao āpau, ka mea i kapa ʻia ʻo isotropy.Ke kila uila i hoʻopili ʻiaʻO ka maʻamau he 3% silicon a hana ʻia ma ke ʻano e hoʻomohala ai i nā waiwai i makemake ʻia ma ke kuhikuhi ʻōwili. ʻOi aku ka liʻiliʻi o ke kumukūʻai o ke kila kila ʻaʻole i ʻōwili anu ʻia (CRNGO) ma mua o ke kila kila ʻaʻole i ʻōwili anu ʻia (CRGO). Hiki ke hoʻohana ʻia ʻo CRNGO no nā noi i hoʻonohonoho ʻia i ke kumukūʻai kahi i paʻa ʻole ai ke kuhikuhi o ka flux magnetic, e like me nā motika a me nā mea hana. ʻO ka CRGO maʻamau ma ke ʻano o kahi coil, pono e ʻoki hou ʻia i loko o nā laminations no nā noi kumu transformer, e like me kekahi mau ʻāpana kūloko i nā mea hoʻololi leo leo.
Ke kila silikaʻo ia ka mea magnetic koʻikoʻi loa i nā noi ʻoihana. ʻO nā noi maʻamau e pili ana i nā generators, nā relays voltage a i ʻole nā ​​​​​​mea hoʻololi pulse i ka ʻoihana kaʻa a me ka mea hoʻololi
