ʻO ke kuhikuhi o ke kahe magnetic i hana ʻia e kahi magnet mau loa mai ka N-pole a i ka S-pole.

Ke kau ʻia kahi alakaʻi i loko o kahi kahua magnetic a kahe ke au i loko o ke alakaʻi, pili ke kahua magnetic a me ke au kekahi i kekahi e hana i ka ikaika. Ua kapa ʻia ka ikaika he "ikaika Electromagnetic".

ʻO ke kānāwai lima hema o Fleming e hoʻoholo i ke kuhikuhi o ke au, ka ikaika magnetic a me ke kahe. E kīkoʻo i ka manamana nui, ka manamana lima kuhikuhi a me ka manamana lima waena o kou lima hema e like me ka mea i hōʻike ʻia ma ke Kiʻi 2.

Ke ʻano o ke au ka manamana waena a ʻo ka manamana kuhikuhi ke kahe magnetic, hāʻawi ʻia ke kuhikuhi o ka ikaika e ka manamana nui.

2. Kahua Magnet i hana ʻia e ke au

3）。Hana nā kahua magnetic i hana ʻia e ke au a me nā magnet mau loa e hana i ka ikaika electromagnetic.

Ke kahe ke au i loko o ke alakaʻi i ka mea heluhelu, e hoʻopuka ʻia ke kahua magnetic ma ke kuhikuhi CCW a puni ke kahe o ke au e ka lula wili ʻākau (Kiʻi 3).

3. Ke komo ʻana o kahi laina o ka ikaika magnetic

Hoʻopilikia nā kahua magnetic i hana ʻia e ke au a me nā magnet mau loa kekahi i kekahi.

ʻO ka laina o ka ikaika magnetic i puʻunaue ʻia ma ke kuhikuhi like e hana e hoʻonui i kona ikaika, ʻoiai ʻo ke kahe i puʻunaue ʻia ma ke kuhikuhi ʻē aʻe e hana e hoʻemi i kona ikaika.

4. Ka hana ʻana o ka ikaika electromagnetic

He ʻano ko ke kaha o ka ikaika makeneka e hoʻi i ka laina pololei ma o kona ʻume ʻana e like me ke kāʻei elastic.

No laila, ua koi ʻia ke alakaʻi e neʻe mai kahi i ʻoi aku ka ikaika o ka ikaika magnetic i kahi i nāwaliwali ai (Kiʻi 5).

6. Hana ʻana o Torque

Loaʻa ka ikaika electromagnetic mai ka hoʻohālikelike;

Hōʻike ʻo Fig.6 i ka torque i loaʻa ke kau ʻia kahi alakaʻi hoʻokahi-huli i loko o ka waihona magnetic.

Loaʻa ka torque i hana ʻia e ke alakaʻi hoʻokahi mai ka hoohalike;

T'(torque)

F (ikaika)

R (mamao mai ke kikowaena a i ke alakaʻi)

Maanei, aia ʻelua mau alakaʻi i kēia manawa;
