The figure below shows the end view of four long parallel wires (labeled 1 through 4) each with a current of 8.40 A arranged in a square with sides of length 0.380 m. The current direction is out of the page for wires 1 and 2 and into the page for wires 3 and 4. Write a vector expression for the magnetic field at the point P which is at the center of the square.
Question 4
One long wire lies along an x axis and carries a current of 46 A in the positive x direction. A second long wire is perpendicular to the xy plane, passes through the point (0, 7.0 m, 0), and carries a current of 53 A in the positive z direction. What is the magnitude of the resulting magnetic field at the point (0, 2.0 m, O)? Number i Units uT
