Basically, you select some loop (i.e., a closed path through space), and walk along the. Ampere’s Law. The magnetic field in space around an electric current is proportional to the electric current which serves as its source, just as the electric field in.

I’m having trouble understanding the surface used for Ampere’s Circuital Law. In classes, we’ve been using simple circular or rectangular loops. Is the surface supposed to be area of the circle or the rectangle? Or is it a simple case of the law?

A example would be the surface used for displacement current. This one is just lost on me. The surface looks like a pot enclosing the wire and the capacitor.

Does the circuiyal specify a closed loop of a surface? The value of the right-hand side is independent of the surface chosen. Then take the difference in the right-hand side evaluated on the two surfaces. Note that this depends crucially on the displacement current term.

If it is omitted, then the right-hand side may differ for two choices of the surface, if charge is building up in cirduital volume between them. In many textbooks, this discrepancy is used to motivate the presence of the displacement current term. The solid angle subtented by a closed surface at an internal point P is 4 pi. Take a closed surface and divide it into two partsupper and lower.

The lower surface subtends an angle omega1 and the upper surface an angle omega2′. Fold the lower surface upwards so circuuital the upper surface is concave and the lower surface is convex.

Let the selected point P be inside the surface. Bring the two parts of the surface so close that the distance of separation is infinitesimally small.

Let the point P be circuiyal inside the surface. Now reverse the upper surface so that it becomes convex; the solid angle omega2′ revereses in sign. Use the expression for the dipole potential for point at point P.

Ampere’s Circuital Law

No matter what surface you choose, the integral will evaluate to the same result. This freedom is what allows us to arbitrary choose the simplest surface possible to evaluate the integral whenever we can. Okay, that edit made everything clear. The diagram in the book made it look like there were two boundary loops for S2.

Very closely related physics. The surface can be any orientable surface whose boundary is the chosen loop. Brian Bi 2, 10 The Dark Side 2, 5 20 S K Gosavi 1.
