The line integral of a magnetic field (B) between two points can be calculated using the equation ∫B · ds. In this context, the wire carrying current is oriented perpendicularly to the page, with the current directed into the page. The magnetic field generated by this configuration follows the right-hand rule, creating circular field lines around the wire. Understanding the orientation of ds relative to the wire is crucial for accurately computing the integral.
