Consider a loop of wire of radius a carrying a current I. The x-axis is perpendicular to the loop and passes through its center with the origin at the center of the loop. Looking in the positive x-direction at the loop from a point on the negative x-axis the current is clockwise. Make a dimensionless plot of the x-component of the magnetic field versus x/a along the x-axis where a is the radius of the loop (plot for -5.0 ? x/a ? 5.0).
