ʻO ka hao-nickel alloy ka hapa nui i ka hoʻohana ʻana i ke kahua mākēneki, ʻoi loa no ka hao ʻauamo, relay, nā mea hoʻololi mana liʻiliʻi a me ka pale Magnetically.
Permalloy magnetic shielding e hana: I mea e pale aku ai i ka hoʻopilikia ʻana o waho o waho, pinepine i ka CRT, kahi ʻāpana CRT electron beam e kālele ana me ka pale magnetic, hiki iā ʻoe ke pāʻani i ka hana o ka pale magnetic.
