Awire runs along the y-axis with a current of 8.00 a running through it in the -y direction. a) p& c: if the wire is infinitely long, what is the magnetic field, b, at (10 m, 0 m, 0 m)? b) calculus: if the wire runs from the origin to the point (0 m, 5 m, 0 m), what is b at (10 m, 0m, 0 m)? c) if the wire runs from (0 m, -5 m, 0 m) to (0 m, 5 m, 0 m), what is b at (10 m, 0 m, 0 m)?
