Two long-length rectilinear conductors are positioned vertically to the page level, as shown in the figure below.

Two long-length rectilinear conductors are positioned vertically to the page level, as shown in the figure below. The conductor 1 is leaked by current I1 entering the page (in the -z direction, to the negative z axis). The duct is located at x = + a, x-axis. The second conductor is located at the point x = -2a of the x-axis and is leaked by a convection current I2. The total magnetic field at the beginning of the axes due to the two ducts has a measure B=2μ0I1/ 2πα

Calculate the potential values of current I2.
