When we apply ampere's circuital law to finite length wire,we get the wrong answer.Why is that? The symmetry rule is being followed,so thats not the problem.(adsbygoogle = window.adsbygoogle || []).push({});

Is it because a finite length wire means that charge is piling up somewhere which means that the current is not steady?
