WebAmpere's Law states that for any closed loop path, the sum of the length elements times the magnetic field in the direction of the length element is equal to the permeability times the electric current enclosed in the loop. In the electric case, the relation of field to source is quantified in Gauss's Law which is a very powerful tool for ... WebWe need the current I passing through the area enclosed by the path. It’s equal to the current density J times the area enclosed. Since the current is uniform, the current …

WebJul 13, 2024 · A current is the steady, predictable flow of one fluid within the body of another fluid. Fluids are materials capable of flowing and easily changing shape. The … WebSep 2, 2024 · Actually the statement and converse are both true. If by statement we mean: $\oint \vec{B} \cdot d\vec{l}=0 \implies $ enclosed current is zero And converse: Enclosed current zero $ \implies \oint \vec{B} \cdot d\vec{l}=0 $. This does not imply no field through the surface defined by the loop, just that it integrates to zero around the path of the loop … WebMay 27, 2006 · If you know the net current enclosed in an amperian loop is zero, when can you conclude that the field at every point on the loop is zero? Here's my actual problem. Part a), I'm pretty sure I did fine (B= u0*I/ (2*pi*r)). Part b) I'm guessing that B equals 0 at any radius r greater than c. The symmetry tells me intuitively that I'm correct, but ... tsh levels for women over 60
