E rua ngā kaiārahi hiko whakarara e kawe ana i ngā iahiko – ngā raruraru me ngā otinga

1. Ko te waea P e kawe ana i te iahiko 6-A ki runga e whakaaturia ana i te pikitia i raro nei. Mena ko µ _o = 4π.10 ^-7 wb A ^-1 m ^-1 , ā, he kaha pana kei waenganui i te waea P me Q 1.2.10 ^-5 Nm ^– 1. Tātaihia te rahi me te ahunga o te iahiko hiko i runga i te waea Q.

E hiahiatia ana: Te rahi me te ahunga o te iahiko hiko i runga i te waea Q

Rongoā:

Ko te ahunga o te iahiko i runga i te waea Q:

He kaha pana kei waenganui i te waea P me Q, ā, he rerekē te ahunga o te iahiko i runga i te waea P ki te ahunga o te iahiko i runga i te waea Q.

I runga i te waea P, kei runga te iahiko hiko, ā, kei raro te iahiko i runga i te waea Q.

Te au hiko i runga i te waea Q:

2. E rua ngā waea e whakarara ana, a L, me M, he 2-cm te tawhiti (tirohia te pikitia). He 4-A te iahiko o te waea M. He kaha panapana kei waenganui i ngā waea e rua, 6 x 10 ^-5 Nm ^-1 . Tātaihia te rahi me te ahunga o te iahiko hiko ki runga i te waea L. (µ _o = 4π.10 ^-7 Wb.A ^-1 m ^-1 )

E hiahiatia ana: Te rahi me te ahunga o te iahiko hiko i runga i te waea L

Rongoā:

Te ahunga o te iahiko i runga i te waea L:

He kaha pana kei waenganui i te waea L me te waea M, ā, kei te taha kē te ahunga o te iahiko i runga i te waea L ki te ahunga o te iahiko i runga i te waea M.

I runga i te waea M ka anga whakarunga te iahiko, kia anga whakararo ai te iahiko i runga i te waea L.

Ko te ahunga o te iahiko i runga i te waea Q:

He kaha kukume kei waenganui i te waea P me te waea Q, ā , ka rite te ahunga o te iahiko i runga i te waea P ki te ahunga o te iahiko i runga i te waea Q.

I runga i te waea P, ko te ahunga o te iahiko kei raro, pērā anō i runga i te waea Q, ko te ahunga o te iahiko kei raro.
