Nā Piko Demagnetization

ʻO ka pākana Demagnetization, a i ʻole ʻo ka piʻo BH ka lua o ka quadrant o ka hysteresis no nā mea ʻume mākeneka paʻakikī e like me nā mākēneki honua ʻike ʻia. Hāʻawi ia i ka ʻike e pili ana i nā ʻano magnet o ka Mākēneki, me ka ikaika o ka māla a me ke kūpaʻa ʻana e demagnetize. ʻO ke kāʻei i ke ana wela kiʻekiʻe e hāʻawi i nā kuhikuhi nui no nā ʻenekini e helu a ʻike i nā mea magnet a kūpono a me ka papa e kū ai i kā lākou koi hana. No laila mākou e hoʻomākaukau iā ʻoe i nā pale demagnetization ma nā mahana hana he nui no nā mākēneka Neodymium sinter a me nā mākēneki Samarium Cobalt i mua i kēlā me kēia papa i loaʻa. E ʻoluʻolu e kaomi i kēlā me kēia cell no kāna mau pākana demagnetization.
