If we want to find out the net magnetic field on a point near a conducting wire , we use ampere's law by take a closed surface in form of A CIRCLE...with radius equal to the distance of the point fromt he where...but where ampere fails is that it gives the same result for both a finite conductor and infinite conductor because the formulae does not deal with the length of the conductor.(adsbygoogle = window.adsbygoogle || []).push({});
