Nā noi o nā Magnets

Hoʻololi ka wili liʻiliʻi o ka uea a me ka magnet i loko o kahi leo i ka hōʻailona uila i nā haʻalulu kani. Hoʻohana pū nā mea hana i nā magnet e hoʻololi i ka ikehu mechanical i ka ikehu uila. A aia mau lākou ma nā wahi ʻē aʻe o nā ʻano mīkini a i ʻole uila e hoʻohana ai i nā magnet e hoʻololi i ka ikehu uila i ka ikehu mechanical.

Hiki i kēia mau magnet ke kōkua i nā cranes e hoʻoneʻe i nā ʻāpana metala nui ʻaʻole hiki ke hāpai ʻia e ke kanaka. Hoʻohana ʻia nā mākēneki i ka hoʻokaʻawale ʻana a me ka kānana ʻana i nā ʻano metala mai nā pōhaku i ʻoki ʻia. Hoʻohana pū ʻia lākou i nā ʻoihana hana meaʻai e hoʻokaʻawale i nā ʻāpana metala liʻiliʻi mai nā kīʻaha. Aia nā noi like ʻole o kēia mau magnet e haʻi wale i nā mea i luna.

Nā hemahema o nā Mākēneki

ʻO kēia kekahi mau hemahema nui o nā magnet ma luna. ʻO nā ʻōpala a me nā mea i hoʻopaʻa ʻia ma hope e hana i nā magnet ferrite. No laila, paʻakikī loa lākou i ka mīkini, no laila, ʻo ka hapa nui o nā huahana ferrite he ʻano maʻalahi loa a me nā hoʻomanawanui nui. He palupalu loa ka magnet Samarium Cobalt, he mea paʻakikī ke hana i nā huahana liʻiliʻi. Hoʻopau ʻia ka hapa nui o nā magnet i nā wela kiʻekiʻe loa a he drawback nui kēia o nā magnet. Eia kekahi, ua maʻalahi nā neodymium magnet a no laila pono e pena ʻia.

Ka hopena

Hiki mai nā mākēneki ma nā ʻano like ʻole, mai nā magnet bar maʻalahi a i nā magnet ʻoihana nui loa. ʻElua mau pou o kēlā me kēia ʻano magnet a inā ʻoki ʻia i ka hapalua, e mau ana kēia mau pou ʻelua. He mea koʻikoʻi nui nā mākēneki i ke kaiāulu kanaka, akā naʻe hiki ke hoʻopau ʻia lākou i nā wela a me ke kaomi.
