Hiki ke heluʻia nā magnenes i kekahi o nāʻanoʻelua o nāʻanoʻelua: mau loa a me ka manawaʻole. Mau magnet mau magnetas i loko o ka "ma ke kūlana; ʻO ia,ʻo kā lākou māla hana mau a hana mauʻia a hōʻikeʻia. ʻO kahi magnet pōkole kahi mea e lilo ai i mea i lilo i ka wā i hanaʻia ma keʻano he marnetic i loaʻa. Malia paha ua hoʻohanaʻoe i kahi magnet e pāʻani me nā lauoho o kou makuahine i ke keiki. E hoʻomanaʻo pehea e hiki ai iāʻoe ke hoʻohana i kahi lauoho lauoho e hoʻopiliʻia i kahi magnet e kiʻi i ka lua eʻohi i kahi lua? ʻO ia no ka liloʻana o ka lauoho mua i kahi magnet pōkole, mahalo i ka ikaika o ka pā o ka marnetic a puni. ʻO nā electromagnet heʻano o ka marnet e lilo ai i "ikaika" i ka wā e hele wale ai kahi mea kūʻai aku ma waena o lākou e hana ana i kahi kahua magnetic.
He aha ka mea alkin magnet?
He nui nā lā magnetos i kēia lā,ʻo Alnio "Maginos, kahi inoa i loaʻa mai i nā'āpana o ka poʻe koa i hanaʻia e Alminum ʻO nā poʻe Alinic egnets ka maʻamau maʻamau a iʻole he mau wāwae wāwae paha. I loko o kahi pahu bar magnet, e kū pono ana nā poli ma nā kihi o ka pahu,ʻoiai i loko o kahi māla lio, e hui pū ana nā pua o nā lio. Hiki ke hakuʻia nā bar magnenets i nā waiwai o nā mea waiwai - neodymium a iʻole samarium cobat. Loaʻaʻia nā pahu pahu pahuʻelua ʻO keʻano e hoʻohanaʻia ai ka mea maʻamau e pili ana i ka noi no ka mea e hoʻohanaʻia ai ka magnet.
Ua hakiʻia kaʻu magnet iʻelua. E hana mau anei?
Ma waho aʻe o kekahi mau liloʻana o ka magnetism ma ke kihi wāwahi, kahi magnet i wāwahiʻia e like me nā meaʻelua, nā mea nui e like me ka ikaika.
Ka hoʻoholoʻana i nā pou
ʻAʻole i hōʻailonaʻia nā magnet āpau me "n" a "a" s "e hoʻolālā i nā pou. E hoʻoholo ai i nā poles o kahi pahu bar-tyg magnet, e kau i kahi pākaukau kokoke i ka magnet a nānā i ka pono; ʻO ka hopena i nā manawa maʻamau i nā wahi'ākau o ka honua e lele ana e holo a puni a hiki i kaʻaoʻao hema o ka magnet. ʻO kēia no ka mea, kokoke loa ka magnet i ke paniʻana, e pili ana i kahi mea ikaika eʻoi aku ka ikaika ma mua o ka honua o ka honua. Ināʻaʻohe o kahi hui, hiki iāʻoe ke holoi pū i ka pahu i loko o kahi pahu wai. E holoi mālie ka magnet a hiki i kona pile'ākau i kūʻia me ka'ākau o ka honua. ʻAʻohe wai? Hiki iāʻoe ke hoʻokō i ka hopena like ma ka hoʻokuʻuʻana i ka magnet i kona kikowaena me ke kaula, eʻae ana e neʻe i ka neʻeʻana.
Nā helu magnet
Ua heluʻiaʻo Bar Magnets e like me nā anaʻekolu:ʻO ke komoʻana o ke koena (br), e hōʻike ana i ka ikaika o ka magnet; ka ikaika nui (bhmax), e ana i ka ikaika o ka pā kula ma ka nui o ka pā o ka nui a me ke kaha ikaika
Aia i hea ka ikaika magnetic e ikaika ana i ka magnet?
ʻO ka ikaika magnetic o kahi bar magnet he kiʻekiʻe loa a iʻole ka mea i hoʻopiliʻia ma ka hope a me ka nāwaliwali ma waena o ka magnet a me ke kikowaena ma waena o ka pou a me ke kikowaena o ka pou. Ua like ka ikaika ma ka pou. Inā loaʻa iāʻoe i nā kānana hao hao, e ho'āʻo i kēia: E kau i kāu magnet ma kahi pākaukau, e hoʻomaʻemaʻe i kaʻaoʻao. 'Ānō e pīpī i nā poni hao a puni. E neʻe aku nā kānana i kahi kūlana e hāʻawi ai i kahi hōʻike hōʻikeʻike o kāu magnet
Ke mālama nei i nā pā
E mālama pono i nā magnet e hana ana ma kā lākou maikaʻi loa, pono e mālama pono e hōʻoia pono e mālama ponoʻia.
Akahele i ka laweʻana i nā magnenets e hoʻopili pū kekahi i kekahi; E makaʻala nō hoʻiʻaʻole eʻae i nā magnet e hoʻokūkū pū me kekahi i ka waihoʻana iā lākou i ka waihoʻana. Hiki i nā collis ke hōʻeha i ka pōʻino i ka magnet a hiki nō ke hōʻeha i nā manamana lima e hele mai ma waena oʻelua mau hōʻailona nui
E koho i kahi pahu paʻa no kāu mau magnet e pale ai i nā lepo metallic mai ke liloʻana i nā magnet.
Kūʻai aku i nā magnet i nā kūlana hoihoi; ʻO ka manawa, ua mālama kekahi mau magnets i nā kūlana hou e hiki ai ke lilo i ko lākou ikaika.
Hale kūʻai alnico magnettion me nā "kahu kahu," nā papa i hoʻohanaʻia e hoʻopili i nā polu o nā mea nui Kōkua ke kōkua i ka paleʻana i nā magnet i lilo i hana i ka hanaʻana i ka manawa.
Mālama i nā mea mālama mālama i nā kamepiula, VCRS, nā kāleka hōʻai'ē a me nā mea hana a me nā microcties a iʻole nā microchips.
E mālama pū i nā magnet ikaika i kahi wahi i loaʻa mai i kahi'ē aʻe e kipaʻia e nā mea hana ma nā pacemaker i mea e hoʻonui ai i ka pacemaker.
