ʻO ke kila silikoni ka 1.0-4.5% silika a me ke kila kila kila me kahi mea kalapona ma lalo o 0.08% i kapa ʻia he kila silika.
Loaʻa iā ia nā hiʻohiʻona o ka permeability magnetic kiʻekiʻe, ka coercivity haʻahaʻa, a me ka resistivity nui, no laila he liʻiliʻi ka hysteresis loss a me eddy current loss.
Hoʻohana nui ʻia e like me nā mea magnetic i nā kaʻa, nā transformers, nā mea uila a me nā mea uila.
