Compute the correct answer of the following problem
Problem- A current I flows in a semi-infinite straight wire along y = 2b, z = 0 from very large positive values of x to the point (0,2b,0), then around a semicircular wire centered upon (0,b,0) and in negative values of x in the z = 0 plane to the point (0,0,0), then along a second semi-infinite straight wire along y = 0, z = 0 from the point (0,0,0) to very large positive values of x.
Part 1- Find the magnetic field (using vector notation) produced at the point (0,b,0).
Clue: for the two straight wires see the hint for question 1. For the semicircular wire, use the Biot-Savart law. Add the results vectorially? What are their individual directions?
I want assist to determine the magnetic field produced at given point.
