Hiki ke ʻike ʻia ke keleawe e "hakakā" i kahi magnet ʻoiai ʻaʻole ia he ferromagnetic.
ʻO ke kumu eddy au, ʻaʻole magnetism maʻamau. Ke hoʻololi ʻia kahi māla magnetic e pili ana i ke keleawe, ʻO ka hoʻoili uila kiʻekiʻe o ka metala e hiki ai i nā ʻōpuni e hana i loko.
Hoʻokumu kēlā mau au i kā lākou māla magnetic, e kū'ē ana i ka hoʻololi i hana iā lākou. Hiki i ka hopena ke hoʻopaʻa ikaika a i ʻole ka hopena damping.
No ke aha e lohi ai ka magnet i ke keleawe
ʻO ia ke kumu o ka hāʻule ʻana o ka magnet i loko o kahi paipu keleawe e lohi nui ai, a i ʻole no ke aha e hiki ai i kahi magnet neʻe kokoke i ke keleawe ke ʻike i ke kūʻē.
ʻAʻole huki ʻia ke keleawe e like me ka hao; ', ʻO ke kahua hoʻololi ke hoʻoulu nei i nā au e hoʻihoʻi i ka neʻe.
Ma nā ʻōlelo ʻenekinia, e pili ana ke keleawe me ka magnet electromagnetically, ʻaʻole ferromagnetically.
E ʻike nui ʻia kēia hopena ma nā kūlana ʻekolu. Ka mua, ke neʻe ka magnet e pili ana i ke keleawe. Ka lua, i ka wā e hoʻololi ai ke kahua magnetic.
Ke kolu, ke mānoanoa ka ʻāpana keleawe a lawa ka conductive no ke kākoʻo ʻana i nā au e holo ikaika ana.
No ka mea, he conductor maikaʻi ke keleawe, ʻoi aku ka maikaʻi o ka hana ʻana i kēia mau au kū'ē.
ʻO ia ke kumu e pono ai ke keleawe i ka braking magnetic, ʻōnaehana hoʻokomo, a me nā noi pale electromagnetic.
No ke aha i manaʻo ai kekahi mau mea "keleawe".
Aia kekahi kumu ʻelua e ʻike ʻia ai nā mea keleawe: aole paha he keleawe maemae.
ʻO nā mea liʻiliʻi o ka hao hao, papa ʻaina, a i ʻole nā mea hoʻohui alloying hiki ke hoʻololi i ka pane ʻike.
Ma ka hana maoli, he keleawe maoli paha kekahi hapa "keleawe"., bronze, keleawe i uhi ʻia, a i ʻole kahi ʻāpana haumia i loaʻa i nā mea ferromagnetic lawa e huki iki i kahi magnet.
Ma ia mau hihia, hele mai ka magnetism mai ka haumia a i ʻole ka hao, aole no ke keleawe ponoi.
No laila ua nuanced ka pane piha: ʻAʻole magnetic ke keleawe maʻemaʻe ma ke ʻano maʻamau, akā hiki iā ia ke launa pū me nā magnet ma o nā au i hoʻokomo ʻia ke hoʻololi ke kahua.
ʻO ia ke kumu he nonmagnetic ke keleawe i ka lawelawe ʻana i kēlā me kēia lā, akā pili loa i ka ʻenehana electromagnetic.
5. No ke aha i ʻike ʻia ai kekahi mau mea keleawe
Ke kumu o ka huikau: ʻaʻole he keleawe maʻemaʻe ka metala
ʻAʻole hana like ke keleawe maʻemaʻe e like me ka metala magnetic ma ke ʻano maʻamau. Akā naʻe,, he nui nā huahana "copper" maoli aole keleawe maemae.
He mau alui keleawe paha, keleawe hana hou, ʻāpana ʻāpana, a i ʻole nā lako hana ʻenehana i loaʻa ka trace ferromagnetic contamination.
ʻO ia ke kumu e pane aku ai kekahi mau mea kala keleawe i kahi magnet inā ʻaʻole hōʻike ka metala keleawe i ka ferromagnetism..
I ka hoʻomaʻamaʻa, ʻO ka magnetism ʻike pinepine ʻia mai kekahi o nā kumu ʻekolu:

ʻŌlelo kēlā, ʻo ka pane pololei e pili ana i ka papa. Inā loaʻa i ka hao ka hao, nickel, a i ʻole nā mea hoʻohui magnetic ʻē aʻe, a i ʻole inā ua haumia i ka wā e hoʻoheheʻe ai a i ʻole ka mīkini, hiki ke hoʻololi i ke ʻano hana magnetic.
No laila, ʻo ke ala kūpono, ʻaʻole ia e manaʻo he nonmagnetic kēlā me kēia huila kala keleawe, akā e nānā pono i ka haku mele.
No ke aha e like paha nā huahana keleawe i hana hou ʻia
Loaʻa pinepine ʻia ke keleawe ʻoihana hana hou i nā koena mai ka mīkini, kaawale ana, a i ʻole nā kūlana lawelawe ma mua.
Nā ʻāpana hao liʻiliʻi, lepo kila, a hiki i nā ʻōpala ferromagnetic ʻē aʻe ke hoʻopili ʻia i ka ʻili a i ʻole i hoʻokomo ʻia i loko o ka mea.
E ʻohi maʻalahi ka magnet i kēlā mau ʻāpana, ka mea e hana ai i ka manaʻo he magnetic ke keleawe ponoʻī.
He kumu maʻamau kēia o ka huikau ma nā hale hana a me ka mālama ʻana i nā ʻōpala. ʻAʻole pane ka magnet i ka matrix keleawe; e pane ana i ka paio.
