Yog ib nqa tam sim no conductor yog muab tso rau hauv ib qho chaw sib nqus , nws ntsib lub zog Lorentz (tshwj tsis yog lub kaum sab xis ntawm qhov ntws ntawm tam sim no thiab cov kab hlau nplaum yog 0 °).

Tseem yuav paub yog, yuav ua li cas tshwm sim thaum lub caij nqa tam sim no muab tso rau hauv ib qho chaw sib nqus sib nqus?

Raws li magnetic teb yog khaub ncaws yog li nws qhov kev hloov pauv nrog lub sijhawm yog xoom. Los ntawm Faraday txoj cai ntawm induction, tsis muaj emf induced. Tab sis tam sim no nqa coil paub torque sab hauv magnetic teb , uas yog cross khoom ntawm Sib nqus lub sijhawm ntawm coil thiab cov magnetic teb.

Ib yam li ntawd, yuav ua li cas tshwm sim thaum tus ntsia thawv hlau khaws cia rau hauv lub caij nqa tam sim no? Thaum koj tso ib qho hlau ntsia hlau hauv tam sim no nqa coil , nws tau magnetized ib ntus. Yeej nws pib ua zoo li electro-magnet. Thaum koj tshem tawm cov khoom siv lub ntsia thawv yuav tau demagnetized dua.

Ib sab saum toj no, yuav ua li cas tshwm sim thaum lub voj voog tam sim no nqa coil tso rau hauv magnetic teb?

Raws li cov nqa tam sim no tus neeg xyuas pib ntsib lub zog thaum tso hauv a magnetic teb ,sib a tam sim no nqa rectangular coil ntsib ib lub zog hauv a magnetic teb . kev taw qhia ntawm quab yuam yog perpendicular rau lub dav hlau uas muaj QR thiab B. Nws yog qhia downward kev taw qhia raws li qhia nyob rau hauv daim duab.

Thaum twg cov hlau nqa tam sim no muab tso rau hauv qhov chaw sib nqus muaj zog?

Thaum muaj tam sim no - nqa hlau yog muab tso rau hauv ib qho chaw sib nqus muaj zog , tsis muaj zog ua rau lub hlau . Dab tsi orientation ntawm hlau yuav zoo li cas? Cov tam sim no thiab cov hlau yog taw tes rau tib qho kev taw qhia (parallel) ntawm magnetic teb , uas ua rau xoom degree kaum sab xis, uas ua rau tsis muaj zog ua rau lub hlau.
