The drawing shows an end-view of two wires. They are long, straight, and perpendicular to the plane of the paper. Their cross sections lie at the corners of a 0.3-m square. The current in wire 1 is going into the page and it is equal to 13 A and the current in wire 2 is going out of the page and it iis equal to 14 A respectively. What is the magnitude of the magnitic filed at one of the emty corner? T

Explanation / Answer

Bx = -?i2/2?a = -4*3.14e-7*14/(2*3.14*0.3) = -9.3333e-6 T >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> By = ?i1/2?a = 4*3.14e-7*13/(2*3.14*0.3) = 8.6667e-6 T >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> B = ?(9.3333e-6*9.3333e-6 + 8.6667e-6*8.6667e-6) = 1.27e-5 T
