1. The problem statement, all variables and given/known data A straight wire caries a 10.0−A current (the figure(Figure 1) ). ABCD is a rectangle with point D in the middle of a 1.10−mm segment of the wire and point Cin the wire. Find the magnitude and direction of the magnetic field due to this segment at the following points. 2. Relevant equations dB = μ*i/4*pi*r ds B = μ*i*L/4*pi*r 3. The attempt at a solution to find the magnetic field at A, would i integrate along ds to get to the second equation then plug in the necessary information?
