FB . Lus Nug: Kev taw qhia ntawm Magnetic Force.

Ib yam li ntawd, tej zaum koj yuav nug, dab tsi yog lub zog sib nqus hauv cov lus yooj yim?

Sib nqus quab yuam , attraction los yog repulsion uas tshwm sim ntawm hluav taws xob nqi hais vim lawv cov lus tsa suab. Nws yog qhov yooj yim zog lub luag haujlwm rau cov teebmeem xws li kev ua haujlwm ntawm lub tshuab hluav taws xob thiab kev nyiam ntawm cov hlau nplaum rau hlau.

Tsis tas li ntawd, electromagnetism physics yog dab tsi? Electromagnetism yog ib ceg ntawm physics koom nrog kev kawm ntawm cov electromagnetic quab yuam, ib hom kev cuam tshuam ntawm lub cev uas tshwm sim ntawm cov khoom siv hluav taws xob.

Ib yam li ntawd, nws nug, F qvB sawv cev rau dab tsi?

Magnetic Force 1. Lub zog yog perpendicular rau ob qho tib si lub nrawm v ntawm tus nqi q thiab magnetic teb B. Qhov loj ntawm lub zog yog F = qvB sin θ qhov twg yog cov lub kaum sab xis <180 degrees ntawm qhov nrawm thiab qhov sib nqus.

Puas yog kev ua haujlwm ua los ntawm cov hlau nplaum ib txwm xoom?

Sib nqus tsis muaj zog (net) ua haujlwm . Vim lub Sib nqus lub zog ntawm tus nqi txav yog perpendicular rau qhov nrawm, lub ua haujlwm los ntawm a Sib nqus zog yog xoom . Lub kauj ntawm sab laug ua rau a magnetic teb mus rau sab xis.
