Pehea ka nui o ka ikaika huki o ka magnet?Manaʻo kekahi poʻe hiki i nā mea magnet NdFeB ke huki i nā mea me 600 manawa e like me kona kaumaha ponoʻī.ʻO kēia anei kēia?Aia kekahi ʻano helu helu no ka hoʻomohu magnet?I kēia lā, e kamaʻilio e pili ana i ka "Pulling Force" o nā magnet.
I ka hoʻohana ʻana i nā magnet, ʻo ka flux magnetic a i ʻole ka hoʻoheheʻe ʻana o ka magnetic he mea koʻikoʻi loa ia e ana i ka hana (ʻoi loa i nā kaʻa).Eia nō naʻe, ma kekahi mau kahua noi, e like me ka hoʻokaʻawale ʻana a me ka lawaiʻa magnetic, ʻaʻole ia he ana kūpono o ka hoʻokaʻawale ʻana a i ʻole ka hopena suction, a ʻo ka huki huki magnetic ka mea kuhikuhi ʻoi aku ka maikaʻi.
ʻO ka ikaika huki o ka magnet e pili ana i ke kaumaha o nā mea ferromagnetic i hiki ke huki ʻia e ka magnet.Hoʻopili pū ʻia ia e ka hana, ke ʻano, ka nui a me ka mamao hoʻokalakupua o ka magnet.ʻAʻohe kumu makemakika e helu ai i ka huki ʻana o kahi magnet, akā hiki iā mākou ke ana i ka waiwai hoʻohiwahiwa mākēneki ma o ke ana ʻana i ka mea hoʻokalakupua (e ana maʻamau i ka manaʻo magnet a hoʻololi iā ia i ke kaumaha), e like me ka mea i hōʻike ʻia ma kēia kiʻi.E emi mālie ka ikaika huki o ka magnet me ka hoʻonui o ka mamao o ka mea hoʻohihi.
Inā ʻimi ʻoe i ka helu ʻana i ka mana magnetic ma Google, nui nā pūnaewele e kākau "e like me ka ʻike, ʻo ka ikaika magnetic o NdFeB magnet ma kahi o 600 mau manawa e like me kona kaumaha ponoʻī (640 mau manawa i kākau ʻia)".Inā pololei kēia ʻike a ʻaʻole paha, e ʻike mākou ma o nā hoʻokolohua.
Ua koho ʻia nā mākēneki Sintered NdFeB n42 me nā ʻano like ʻole a me nā nui i ka hoʻokolohua.ʻO NiCuNi ka uhi ʻana o ka ʻili, i hoʻokaʻawale ʻia ma ke ala kiʻekiʻe.Ua ana ʻia ka ikaika tensile kiʻekiʻe (N pole) o kēlā me kēia magnet a hoʻololi ʻia i ke kaumaha huki.Penei na hopena ana.
ʻAʻole paʻakikī ka loaʻa ʻana mai nā hopena ana:
- ʻO ka lakio o ke kaumaha e hiki ai i nā magnet o nā ʻano like ʻole ke huki i ko lākou kaumaha ponoʻī.ʻO kekahi ma lalo o 200 mau manawa, ʻoi aku kekahi ma mua o 500 mau manawa, a hiki i kekahi ke piʻi ma mua o 3000 mau manawa.No laila, ʻaʻole pololei loa nā manawa 600 i kākau ʻia ma ka Pūnaewele
- No ka Cylinder a i ʻole Disc Magnet me ke anawaena like, ʻoi aku ka kiʻekiʻe o ke kiʻekiʻe, ʻoi aku ka nui o ke kaumaha e hiki ke huki, a ʻo ka ikaika magnetic e like me ke kiʻekiʻe.
- No ka Cylinder a i ʻole Disc Magnet o ke kiʻekiʻe like (cell blue), ʻoi aku ka nui o ke anawaena, ʻoi aku ka nui o ke kaumaha e hiki ai iā ia ke huki, a ʻo ka ikaika magnetic e like me ke anawaena.
- He ʻokoʻa ke anawaena a me ke kiʻekiʻe o ka Cylinder a i ʻole Disc Magnet (cell melemele) me ka nui like a me ke kaumaha, a ʻokoʻa ke kaumaha e hiki ke huki.ʻO ka mea maʻamau, ʻoi aku ka lōʻihi o ke kuhikuhi ʻana o ka magnet, ʻoi aku ka nui o ka ʻūhā
- No nā mea magnet me ka leo like, ʻaʻole i like ka mana magnetic.Ma muli o nā ʻano like ʻole, ʻokoʻa paha ka ikaika magnetic.ʻO ke ʻano like ʻole, ʻokoʻa ke ʻano, ka nui a me nā kaupaona like ʻole o nā magnet e huki i ka paona like o nā mea ferromagnetic.
- ʻAʻohe ʻano o nā ʻano, ʻo ka lōʻihi o ke kuhikuhi kuhikuhi ka mea nui loa i ka hoʻoholo ʻana i ka ikaika magnetic.
ʻO ka mea i luna nei ka hoʻāʻo ikaika huki no nā magnet o ka papa like.Pehea e pili ana i ka ikaika huki no nā magnet ʻokoʻa o nā papa ʻokoʻa?E ho'āʻo a hoʻohālikelike mākou ma hope.
