Fa'avasegaga:u'amea fa'amaneta vaivai sa'o
Fa'aopoopoga: U'amea fa'atasi ai ma le maualuga o le permeability i fanua vaivai i le saturation induction 0.65-0.75 T. U'amea fa'atasi 1J79/ maualuga tumau le squareness o le hysteresis loop ma le maualalo o le coefficient o le magnetization reversal
Fa'aoga: Mo ni fatu laiti o transformers, chokes ma relays o lo'o fa'agaoioia i fanua vaivai, talita maneta. I le mafiafia la'ititi (0.05 ± 0.02 mm) - o fatu mo pulse transformers, magnetic amplifiers ma solid state relays
