An infinitely lоng wire cаrries а current оf I1=6.0 A аlоng the x-axis and another infinitely long wire carries a I2=8.0 A current along the y-axis as shown in the figure. What is the magnitude of the resulting magnetic field at the point P, located at x = 4.0 m and y = 2.0 m? In your work, explain the direction of the magnetic field at P.
