Biot Savart Law

  1. Jul 25, 2017 #1
    I've got a question regarding application of the Biot-savart law along finite wire.
    There is a great explenation of this problem in the MIT paper but this does not cover one case.

    1. The problem statement, all variables and given/known data

    My question is: does the equation defining magnetic field in point P(x,y) also applies to the point P_1(x,y) (as in the picture below) which is not in boundaries of the wire?

    2. Relevant equations

    Magnetic field in point P(x,y) (as in the above figure) along finite wire is:

    3. The attempt at a solution
    My guess is: yes, just because I can put P_1 coordinates in the equation, but intuition tells me that I am omitting something and unfortunately I don't know what.

    Yes, but you have to be careful with how you apply Biot-Savart, specifically what is x. You are omitting x1 from the picture.

    In that case I would define x as
    x=L/2 + x_1
