A flat rectangular wire loop is positioned next to a long straight current-carrying wire. Both the loop and the wire are in the plane of the page, and the direction of the current is clearly indicated in the figure. How does the magnitude of the magnetic field change as the perpendicular distance from the wire, (r) increases? From Ampère's Law we know that the magnitude of the magnetic field increases in direct proportion to the perpendicular distance, that is, Bocr. From Ampère's Law we know that the magnitude of the magnetic field decreases as an inverse proportion to the square of the perpendicular distance, that is, Bxc1/r^2. From Ampère's Law we know that the magnitude of the magnetic field decreases as an inverse proportion to the perpendicular distance, that is, Bxc1/r. From Ampère's Law we know that the magnitude of the magnetic field increases in direct proportion to the square of the perpendicular distance, Bocr^2.
