Consider two very long cylindrical wires (see image) of radius R, with current moving in the same direction. The centers of the wires are a distance 4R apart. Both wires have a uniform current density Jo. In the image, the line connecting the centers of the wires is an imaginary line to help visualize distances. a. What is the magnetic field at point (a), midway between the wires? b. What is the magnetic field at point (b) which is a point R/3 from the center of the left wire along the line connecting the two wire centers? c. What is the magnetic field at point (c), the center of the left wire? Side view current flows right Cross - Section View current into page -42
