Hana Magnet mau
ʻO nā holomua ʻenehana he nui wale nō i hiki ke hiki ma hope o ka hoʻomohala ʻana i nā magnet paʻa ikaika loa i nā ʻano like ʻole a me nā nui. I kēia lā, ʻokoʻa loa nā mea magnetic a me nā waiwai mechanical, a no laila hiki ke hoʻohana ʻia nā ʻohana ʻehā o nā magnet paʻa i kahi ākea o nā noi.
Loaʻa iā RUMOTEK Magnet kahi waiwai nui o ka magnet mau loa i nā ʻano like ʻole a me nā ʻano like ʻole me ka noi a ka mea kūʻai aku, a hāʻawi pū kekahi i nā magnet i hana ʻia. Mahalo i ko mākou akamai i ke kahua o nā mea magnetic a me nā magnet mau loa, ua kūkulu mākou i kahi ākea o nā ʻōnaehana magnetic no nā noi ʻoihana.
He aha ka wehewehe ʻana o ka magnet?
ʻO ka magnet kahi mea hiki ke hana i kahi māla magnetic. Pono nā mākēneki a pau ma ka liʻiliʻi hoʻokahi Pole ʻĀkau, a hoʻokahi Pole Hema.
He aha ke kahua magnetic?
ʻO ke kahua mākēnehe kahi wahi o ka lewa kahi e ʻike ʻia ai ka mana magnetic. Hiki ke ana 'ia ka ikaika a me ke kuhikuhi o ka mana magnetic.
He aha ka magnetism?
ʻO ka Magnetism e pili ana i ka ikaika o ka huki ʻana a i ʻole ka repulsion i waena o nā mea i hana ʻia me nā mea kikoʻī e like me ka hao, nickel, cobalt a me ke kila. Loaʻa kēia ikaika ma muli o ka neʻe ʻana o nā uku uila i loko o ke ʻano atomika o kēia mau mea.
He aha ka "mau" magnet? Pehea ka ʻokoʻa me ka "elecromagnet"?
Ke hoʻomau nei ka hoʻokuʻu ʻana i ka mana magnetic me ka ʻole o kahi kumu mana, ʻoiai ke koi nei ka electromagnet i ka mana i mea e hana ai i kahi māla magnetic.
He aha ka ʻokoʻa o ka magnet isotropic a me anisotropic?
ʻAʻole kuhikuhi ʻia kahi magnet isotropic i ka wā o ke kaʻina hana, a no laila hiki ke magnetized i kekahi ʻaoʻao ma hope o ka hana ʻana. ʻO ka hoʻohālikelike ʻana, ʻike ʻia kahi magnet anisotropic i kahi māla magnetic ikaika i ka wā o ka hana hana i mea e hoʻonohonoho ai i nā ʻāpana i kahi kuhikuhi kikoʻī. ʻO ka hopena, hiki ke hoʻopaneʻe wale ʻia nā magnet anisotropic i hoʻokahi ʻaoʻao; akā naʻe, ʻoi aku ka ikaika o nā waiwai magnetic.
He aha ka mea e wehewehe ai i ka polarity o ka magnet?
Inā ʻae ʻia e neʻe kūʻokoʻa, e hoʻopili ʻia kahi magnet me ka polarity ʻākau-hema o ka honua. Ua kapaia ka pou e imi ana i ka hema, o ka "koku hema" a o ka pou e kuhikuhi ana i ka akau, ua kapaia ka "poe akau."
Pehea e ana ʻia ai ka ikaika o ka magnet?
Hoʻohana ʻia ka ikaika magnetic ma nā ʻano like ʻole. Eia kekahi mau laʻana:
1) Hoʻohana ʻia ka Gauss Meter no ke ana ʻana i ka ikaika o ke kahua i hoʻokuʻu ʻia e kahi magnet ma nā ʻāpana i kapa ʻia ʻo "gauss."
2) Hiki ke hoʻohana ʻia nā mea hōʻike huki no ke ana ʻana i ka nui o ke kaumaha i hiki i kahi magnet ke paʻa i nā paona a i ʻole kilokani.
3) Hoʻohana ʻia nā permeameters no ka ʻike ʻana i nā hiʻohiʻona magnetic pololei o kahi mea kikoʻī.
Hale hana
