Kedu ihe jikọrọ ike ndọta nke electromagnet?

Part 1 Olee otú gbakọọ ike nke electromagnet?

Nke mbụ, anyị kwesịrị ịghọta otú magnetism nke electromagnet si eme. Ebe ndọta nke solenoid nwere ọkụ eletrik kwesịrị ịbụ B=u0*n*I dịka iwu Biot-Savart siri dị. B = u0 * n * I , B bụ ike induction magnetik, u0 bụ ihe na-adịgide adịgide, n bụ ọnụ ọgụgụ nke ntụgharị nke solenoid, na m bụ ugbu a na waya. Ya mere, a na-ekpebi nha nke oghere magnet site na nke ugbu a na ọnụ ọgụgụ nke ntụgharị nke solenoid!

Nkebi 2: Mara ihe owuwu nke electromagnet na ụkpụrụ ọrụ?

Electromagnet ma ọ bụ solenoid bụ okwu izugbe maka ụdị ọkụ eletrik niile.

N'ụzọ bụ isi, electromagnets ma ọ bụ solenoids bụ ngwaọrụ na-emepụta oghere magnetik site na eriri igwe ume, na-eduzi ya site na akụkụ ígwè dabara adaba nwere oghere ikuku. N'ebe a, a na-emepụta ogwe ndọta n'etiti nke ike ndọta nke mmasị, ike magnetik, na-emeri.

Ọ bụrụ na ọ dịghị ugbu a etinyere na eriri igwe, ọ dịghị ike electromagnetic na-emepụta; ọ bụrụ na a na-ahazi eriri eriri igwe, enwere ike ịhazi ike ndọta. Dabere n'owuwu nke akụkụ ígwè, a na-eji ike magnetik eme mmegharị ahịrị ma ọ bụ rotary ma ọ bụ iji jide ike na akụrụngwa, na-emebi ma ọ bụ na-edozi ha.

Nkebi 3, igodo na-emetụta ike magnetik?

Enwere isi ihe ise na-emetụta ike magnetik nke electromagnet:

3.1 ọ metụtara ọnụọgụ ọnụọgụ nke ọnya solenoid dị n'ime bobbin. Enwere ike gbanwee ọnụ ọgụgụ ntụgharị nke eriri solenoid site na wiring iji mezie nha nke ike magnetik.

3.2 Ọ metụtara ọkụ eletrik na-agafe na onye nduzi. Enwere ike ịgbanwe ihe na-agafe ugbu a site na onye nduzi site na ịkwanye rheostat, na nke ugbu a nwekwara ike ịba ụba site n'ịba ụba nke ike. Ike karia, siri ike.

3.3 n'ime isi ígwè ga-emetụtakwa ike nke solenoid. Ihe ndọta na-esi ike mgbe enwere isi ígwè, na adịghị ike mgbe enweghị isi ígwè;

3.4. Ọ na-ejikọta ya na ihe ndọta dị nro nke isi ígwè nke onye nduzi.

3.5 Njikọ cross-section nke ígwè isi ga-emetụtakwa ike ndọta.

Summery: mgbe ịmepụta onye na-eme ihe nkiri solenoid, ike na ogologo ndụ yana nkọwapụta, ọ bụrụ na ịchọrọ ịme onwe gị onye na-eme ihe nkiri, onye ọkachamara ọkachamara anyị ga-achọ ka gị na gị nwee mkparịta ụka na ịkọrọ gị ndụmọdụ ọkachamara.
