Raupapa JCTN Te Whakaara i te Tohu Paetahi me te Whakaiti i te Ihirangi Para Pūmau
Whakamahinga:Te tango i te kirikiri mō te rauemi waipuke i muri i te mira tuatahi, i te kukū rānei i mua i te mira tuarua, me te tātari, te tango kirikiri rānei i mua i te whāngai o te magnetite ki roto i te mata pai me te whakatārewatanga whakamuri: te painga whakamutunga mō te magnetite.
Ngā Āhuatanga
1. Whakamahia te taputapu whāngai paipa me te pūnaha rerenga-nui hei whāngai i te rauemi kia ōrite.
2. Me te huānga aukume 200 ~ 270° me te hoahoa maha-pou hei whakatutuki i te mea tino paitohu painga, ka taea te hoahoa i te hanganga huānga aukume kia rite.
3. Pūnaha whakaranu aukume i roto i te tāke.
4. Te whāngai i raro i te wai, te pūwero hurihuri-whakamuri me te wai horoi maha-wāhanga e ranea ana.
5. Pūnaha tukunga e rua ngā wāhanga me te waru PU.
6. Pūnaha taraiwa whakahaere auau.
