A current $I$ is flowing along an infinite, straight wire, in the positive Z-direction and the same current is flowing along a similar parallel wire $5\,\text{m}$ apart, in the negative Z-direction. A point P is at a perpendicular distance $3\,\text{m}$ from the first wire and $4\,\text{m}$ from the second. What will be magnitude of the magnetic field $B$ at P?
