Step 1
First, let's define the coordinate system. We set the origin of our axes at the center of the square loop. The x-axis points to the right, the y-axis points upwards, and the z-axis points out of the page (towards us). Show more…

Consider a flat, circular current loop of radius $R$ carrying current $I$. Choose the $x$ axis to be along the axis of the loop, with the origin at the center of the loop. Graph the ratio of the magnitude of the magnetic field at coordinate $x$ to that at the origin, for $x=0$ to $x=5 R$. It may be helpful to use a programmable calculator or a computer to solve this problem.
