Then with ∮ B → ⋅ d l → = μ 0 I e n c l, with I e n c l = J → ( r) π r 2, the current density times the area. Then calculating J → ( r) is straightforward, as J → ( r) = 2 B 0 μ 0 R e ... WebThe current I = 20.0 A is given, and q = – 1.60 × 10 – 19 C is the charge of an electron. We can calculate the area of a cross-section of the wire using the formula A = πr 2, where r is one-half the given diameter, 2.053 mm.

WebNov 15, 2016 · How to find the cross sectional area of a wire. First, we define that the diameter of our wire is taken in thousandths of an inch where one one-thousandth of an inch is called “one mil.”. Thus, 0.001 inch = 1 mil, 0.01 inch = 10 mils and so forth. Then we define the cross sectional area simply as the square of the wire’s diameter in mils ...
