Two long, parallel wires are separated by a distance of 0.20 m and carry equal currents. There is a force of attraction per meter of 6.5 X 10-5 N/m between them. Find the magnitude of the currents in A and deterimne if they are parallel or anti parallel.
The expert finds the magnitude of the currents in A. The current and force are provided. Seven lines of computations solve this problem.
