    Iecaianoaaiiuo Mākēneki paʻa

    Ua hiki ke loaʻa nā holomua ʻenehana he nui ma hope o ka hoʻomohala ʻia ʻana o nā mākēneki paʻa loa i nā ʻano like ʻole a me nā nui. I kēia lā, ʻokoʻa ʻokoʻa loa nā pono ʻume mākenēki a me ka mechanical, a hiki ke hoʻohana ʻia nā ʻohana ʻehā o nā mākēneki paʻa mau i nā ʻano noi he nui.

    He waiwai nui kā RUMOTEK Mākēneki o ka magnet mau loa i nā ʻano a me nā nui i loli me ka noi a ka mea kūʻai, a hāʻawi pū kekahi i nā mākēneki i hana ʻia. Mahalo i ko mākou mākaukau i ke kahua o nā mea magnet a me nā mākēneki paʻa, ua hoʻomohala mākou i kahi ākea o nā ʻōnaehana magnetika no nā noi ʻoihana.

    He aha ka wehewehe o ka Mākēneki?
    ʻO ka Mākēneki kahi mea hiki ke hana i kahi māla magnet. Pono nā mākēneki āpau ma ka liʻiliʻi i hoʻokahi Pole ʻĀkau, a i hoʻokahi Pole Hema.

    He aha ka māla ʻume mākenēki?
    ʻO kahi māla ʻume mākea kahi ʻāpana o ka lewa kahi kahi e ʻike ʻia ai ka ikaika ʻume mākenēki. Loaʻa ka ikaika a me ke kuhikuhi i ka mana magnet.

    He aha ka magnetism?
    ʻO ka Magnetism e pili ana i ka ikaika o ka hoʻokipa a i ʻole repulsion e kū nei ma waena o nā mea i hana ʻia i nā mea kikoʻī e like me ka hao, nickel, cobalt a me ka kila. Aia kēia ikaika ma muli o ka neʻe o nā koina uila i loko o ke ʻano atomic o kēia mau mea.

    He aha ka Mākēneki "kūmau"? Pehea ia ʻokoʻa mai kahi "elecromagnet"?
    Hoʻomau ka Mākēneki paʻa mau e hoʻokuʻu i ka ikaika a me ka ʻole o ka mana, ʻoiai ka electromagnet e koi ai i ka mana i mea e ulu ai kahi māla magnet.

    He aha ka ʻokoʻa o ka magnet magnet isotropic a me anisotropic?
    ʻAʻole hoʻokumu ʻia kahi magnet magnet isotropic i ka wā o ke kaʻina hana, a no laila hiki ke magnetized i kekahi ʻaoʻao ma hope o ka hana ʻia ʻana. I ka hoʻohālikelike ʻana, hōʻike ʻia kahi magnet magnet anisotropic i kahi māla ikaika ikaika i ka wā o ka hana ʻana i mea e hoʻoliʻiliʻi ai i nā ʻāpana i kahi kuhikuhi kikoʻī. A ʻo kahi hopena, hiki i ka magnet magnet anisotropic ke hoʻopili wale ʻia i hoʻokahi ala; akā, ʻoi aku ka nui o ko lākou mau pono mehana.

    He aha ka wehewehe ʻana i ka polarity o ka magnet?
    Inā ʻae ʻia e neʻe manuahi, e hoʻopili ka Mākēneki iā ia iho me ka polarity ʻākau-hema o ka honua. ʻO ka lāʻau e ʻimi hema ana i kapa ʻia ka "poloka hema" a ʻo ka pou e kuhikuhi ana i ke kūkulu ʻākau ua kapa ʻia ʻo "poloka ʻākau."

    Pehea e ana ʻia ai ka ikaika o ka Mākēneki?
    Ana ʻia ka ikaika Mākēneki i kekahi mau ʻano ʻokoʻa. Eia kekahi mau laʻana:
         1) Hoʻohana ʻia kahi Mīkini Gauss e ana i ka ikaika o ka māla e hoʻopuka ai kahi magnet i nā anakuhi i kapa ʻia ʻo "gauss."
         2) Hiki ke hoʻohana i nā mea hoʻāʻo hukihuki e ana i ka nui o ke kaupaona i hiki i ka maneta ke hoʻopaʻa i nā paona a i nā kilokika.
         3) Hoʻohana ʻia nā Permeameter e ʻike i nā ʻano mākēneki kikoʻī o kekahi mea kikoʻī.
