Line integral of cross product

NettetIt follows from this fact and the definition of the cross-product that where ds is the differential along the line current and Integration of the Biot-Savart law, (7), is first performed over the cross-section of the stick. The cross-sectional dimensions are small, so during this integration, the integrand remains essentially constant. NettetSo the video has vectors A and B and it creates AxB. This new vector AxB is orthogonal to A and it is orthogonal to B because that's what the cross product does. That means AxB (dot) A =0 and AxB (dot) B=0. The video then does the calculations to show that both of those statements are true.

This notation's strength is that it emphasizes the role of a vector field and dot product. Another common notation for the line integral of a vector field P, Q, R along a curve C is . ∫ C P d x + Q d y + R d z. This notation is common in physics and engineering.
