I'll say again about engineers.
The direction of the magnetic field from opposite lengths of wire oppose each other outside the loop and are aligned with one another inside. Therefore it is NOT possible for the magnetic flux density to be higher anywhere than it is at the center of the loop. This is true in the plane of the loop and even more so outside the plane of the loop.
