A current I carried in a conduit as described below. The wire can be assumed to be infinitely long in the positive x-direction. The point P is the radius distance a from the portion of the line that describes a semicircle. Calculate the resulting magnetic field at point P in magnitude and direction.
The Attempt at a Solution
I have calculated the magnetic field caused by the semicircle. I am not quite sure how to calculate the magnetic fields caused by the two infinitely-long wire segments. From my calculations they cancel each other out. Is this correct? Is the magnetic field caused by the semicircle correct?
I have linked my answer below:
Any help is appreciated.
