1j65 Pepa Alu maneta vaivai FeNi65u'amea mageta vaivai o lo'o i totonu o le maneta vaivai ma le permeability maualuga ma le malosi fa'amalosi maualalo o alloys.This ituaiga o u'amea o lo'o fa'aaogaina lautele i leitio fa'aeletonika, meafaigāluega sa'o ma mita, fa'atonu mamao ma le fa'atonuina otometi, o le tu'ufa'atasiga e masani ona fa'aaogaina mo le liua o le malosi ma fa'amatalaga fa'amatalaga, o itu e lua o se mea taua i le tamaoaiga o le atunu'u.
Fa'amama fa'amama maneta fanua fa'amaneta i fafo i lalo o le fa'atinoga o le fa'amaneta faigofie, fa'ato'a mou atu pe a uma ona aveese le fa'amaneta o le malosi fa'aoso fa'amaneta ma alloys maneta.1j65 Su'ega vaila'au.
