He aha ka ʻokoʻa ma waena o ke kaapuni magnetic o kahi magnet ikaika a me nā ʻano kino o ke kaapuni？

ʻO nā ʻokoʻa nui ma waena o nā waiwai kino o nā kaapuni magnetic a me nā kaapuni uila penei:
(1) Loaʻa nā mea conductive maikaʻi ma ke ʻano, a aia kekahi mau mea e hoʻokaʻawale i ke au.No ka laʻana, ʻo ka resistivity o ke keleawe he 1.69 × 10-2Qmm2 / m, ʻoiai ʻo ka resistivity o ka lāʻau ma kahi o 10 mau manawa kiʻekiʻe.Akā a hiki i kēia manawa, ʻaʻohe mea i hoʻopaʻa ʻia i ka flux magnetic i loaʻa.ʻO ka hikiwawe o ka bismuth, nona ka liʻiliʻi liʻiliʻi loa, ʻo ia ka 0. 99982μ.He 1. 000038μ ka mana o ka ea.No laila hiki ke ʻike ʻia ka ea ma ke ʻano he mea me ka haʻahaʻa haʻahaʻa.ʻO ka pili pili o nā mea ferromagnetic me ka permeability maikaʻi loa e pili ana i ke ono o ka mana o 10.

(2) ʻO kēia ke kahe ʻana o nā nui i hoʻopaʻa ʻia i loko o kahi mea hoʻokele.Ma muli o ke kū ʻana o ka conductor, hana ka mana electrodynamic i ka nui i hoʻopaʻa ʻia a hoʻopau i ka ikehu, a hoʻololi ʻia ka nalowale o ka mana i ka wela.ʻAʻole hōʻike ka flux magnetic i ka neʻe o kekahi nuipa, ʻaʻole ia e hōʻike i ka nalowale o ka mana, no laila he hoʻopunipuni kēia hoʻohālikelike.Me he mea la he kaawale ka kaapuni a me ke kaapuni magnetic, a ua loaa i kela mea keia mea kona mau mea pono ole e honi ana i ka manao iloko o ka puolo.He oopa keia hoohalike no ka lilo o ka mana.He ʻokoʻa ke kaapuni a me ke kaapuni magnetic, a loaʻa i kēlā me kēia me kona ʻano kino ponoʻī ʻole.
