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 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.
