Homework Help: Calculating the magnetic field of 3 piece wire

  1. Nov 6, 2005 #1
    Okay I need some verification that I did this problem right. If not then please tell me where I went wrong.

    Given a long wire going into the page with current also going in the same direction and then making a half-circle arc along the plane of the paper to the left, and finaly conituing to make a straight wire. Find the magnetic field at P which is at the center of the arc (center of circle if the arc were a full circle). I'm given the radius of the arc and the current.

    I used phi=Pi
    I attached the formula I used and a poor drawing of what the wire looks like.

    segment. View attachment arc.doc

    I got 1.14X10^-4T
