First, we construct an Amperian loop at a radius r within the wire. We then divide the We then divide the wire into two pieces, a hollow cylinder, and a cylindrical core, as shown in Fig. 8.5.... The net number of perpendicular surfaces pierced by an Amperian loop is proportional to the current passing through the Amperian loop. Ampere’s Law and the Line Integral The net number of perpendicular surfaces pierced by an Amperian loop is proportional to the current passing through the Amperian loop.

We refer to this imagined loop as the “Amperian Loop.” Amperian loop around a line of current Formally, we are doing a path or line integral around a loop with the magnetic field, but for most cases this integral will simplify quite a bit. how to draw the letter h Now In order to calculate the magnetic field due to the uniform current flowing in the Y=0 plane, we need to consider the small portion of the surface and draw appropriate ‘Amperian loop’ enclosing the current and apply Ampere’s law. In this case the amperian loop will be a rectangular box which is parallel to XY plane and extending an equal distance above and below the surface as shown

- We draw an Amperian loop within a wire that carries current uniformly across its circular cross-sectional area. Which describes the value of the integral in Ampere’s law?
- To begin we will place an Amperian loop along the center of the toroid's coils so that its radius, r, lies between the inner and outer radii of the torus, a < r < b. For r < a and r > b, B = 0. In the case of r < a, no currents are enclosed within the Amperian loop.
- ? Consider several small Amperian loop choices, labeled a-d. List ALL of these which might prove useful in learning something quantitative about B ? x , y , z ? some- where . For each loop
- Take your Amperian loop to be a circle with the same center as the tube. In that case, the left-hand side of Ampere’s Law simplifies to [math]2\pi rB,[/math] where [math]r[/math] is the radius of the loop.
