1j65 Pepa Alloy Magnetic palupalu / pā FeNi65Hoʻohana nui ʻia kēia ʻano alloy i ka lekiō uila, nā mea kani a me nā mika, ka mana mamao a me ka ʻōnaehana hoʻokele, hoʻohana nui ʻia ka hui ʻana no ka hoʻololi ʻana i ka ikehu a me ka hoʻoili ʻana i ka ʻike.
ʻO ke kahua hoʻokalakupua maʻemaʻe ma lalo o ka hana o ka magnetization maʻalahi, nalo ke kumu ma hope o ka wehe ʻana o ke kahua magnetic o ka ikaika induction magnetic a me nā alloys magnetic.
