1. The problem statement, all variables and given/known data Three straight current carrying wires for each a current I as shown below. They are in the corners of a square that has sides a. Specify the resulting magnetic field at point P in the lower right corner, give both size and direction of the field. 2. Relevant equations Magnetic Field B = (μ0I)/(2∏r) r = distance I = current 3. The attempt at a solution I have a finished answer to the question but I am not sure if it correct. I have linked a picture of my solution below. http://i.imgur.com/UUx4C8M.jpg I am not sure if i have calculated Bz correctly. Is the Bz that I have calculated correct? Is rest of the solution correct? Any Help is Appreciated.
