Question

Two long straight wires carry currents perpendicular to the
*xy* plane. One carries a current of 45 A and passes through
the point *x* = 5.5 cm on the *x* axis. The second
wire has a current of 80 A and passes through the point *y*
= 4.3 cm on the *y* axis. What is the magnitude of the
resulting magnetic field at the origin?
