The solution of the problem 2.42 cr 2 from the problem

Task 2.42
For two infinitely long rectilinear parallel conductors, the distance between them is 15 cm, the currents 4 and 6 A flow in one direction. Determine the distance from the conductor with a smaller current to the geometrical location of the points at which the magnetic field strength is zero.
