Gade kòd pou Endiktans

[[File:Solenoid-1.png|thumb|Single bobin.]]
Dapre [[teyorèm Anpè]], nenpòt kouran k ap koule nan yon sikwi kreye yon [[chan mayetik]] atravè seksyon li antoure, sa a se fenomèn [[endiksyon elektwomayetik]]. "Endiktans" sikui sa a se kosyan [[Magnetic flux|flux]] nan chan mayetik sa a pa entansite aktyèl la ki pase nan sikwi a<ref name="IEC">{{web link| url=http ://www.electropedia.org/iev/iev.nsf/display?openform&ievref=131-12-19|title=Inductance|publisher=[[International Electrotechnical Commission]]|site=electropedia.org|accessed on =19 fevriye , 2013}}.</ref>{{,}}<ref name="Cessac-Tréherne">Jean Cessac, Georges Tréherne, ''Physique – Classe de Mathématiques'', Paris, {{éd.}} Fernand Nathan , 1957, {{p.|268-270}}.</ref>{{,}}<ref name="cnrtl-1">{{web link|url=http://www.cnrtl. fr/ definition/Inductance|title=Inductance|editè=[[National Center for Textual and Lexical Resources]]|site=cnrtl.fr|accessed on=19 fevriye 2013}}.</ref>.

== Kouran ak chan elektrik ==

{{atik detaye|Lwa Ørsted}}

Nou mete tèt nou nan ka yon [[sikwi elektrik]] ki fòme ak yon sèl may (nan sans [[lwa Kirchhoff yo]]). Se poutèt sa sikwi sa a travèse pa yon konstan [[kouran elektrik]] ''I'' nan tout kous la (men ki eksperyans ka evidamman varye, depi ke li fèt dousman, epi nou pa dirèkteman konsène ak ti efè pasajè akòz varyasyon sa yo).

Jan sa montre nan eksperyans [[Hans Christian Ørsted|Ørsted]], rezilta yo ofisyèlman pa [[Lalwa Ørsted]] la<ref name="Dhogal">{{ouvraj|language=en|name1 =Dhogal|title =Debaz Jeni Elektrik|volim=I|piblikatè=Tata McGraw-Hill|dat=1986|total paj=96|isbn=0074515861|li sou entènèt={{Google Books|iIAisqtIeGYC|paj=PA96|light=oersted's}}}} .</ref>, prezans yon kouran elektrik Lè sa a, kreye yon [[champ mayetik]] nan espas, konfigirasyon egzak la ki ka konplèks, tou depann de layout nan sikwi a li menm potansyèlman konplèks. Dapre lalwa Ørsted a, kontribisyon 'B'' nan [[chan mayetik]] pwen <math>P</math> yon eleman enfinizimal 'l'', ki chita nan pwen <math>Q</math> ak travèse pa ''I'' aktyèl la, se:
:<math>\rm d\vec B_{(P)} = \frac{\mu_0}{4 \pi}I \; \overrightarrow{\rm d\ell} \wedge\left(\frac\overrightarrow{PQ}{|\overrightarrow{PQ}|^3}\right)</math>

Se poutèt sa, nou konnen ke jaden an mayetik prezan nan tout kote nan espas, men nan ka jeneral la, jeneralman pa gen okenn fason pratik yo kalkile valè li yo nan yon pwen espesifik. Men, endepandamman de konpleksite li nan espas, jaden pwovoke sa a se (nan yon premye apwoksimasyon - nan yon vakyòm) pwopòsyonèl nan tout pwen ak kouran elektrik ki te kreye li, epi li se pwen sa a ki se fondamantal pou sa ki annapre yo.
