The loop lies in the x-y plane, centered at the origin and pivoted along the z axis. The direction of the current I in the loop is clockwise. The radius of the loop is a. A point is located at a distance of R on the z-axis from the loop periphery. A vector represents a magnetic field H along the z-axis.

The input value is as follow:

A number line displays numbers from negative 0.2 to 0.2 from left to right. A pointer is highlighted on the line at z-axis location equals 0.05 left bracket meter right bracket.

A number line displays numbers from 0 to 10.0 from left to right. A pointer is highlighted on the line at loop current I equals 1.0 left bracket ampere right bracket.

A number line displays numbers from 0.01 to 0.1 from left to right. A pointer is highlighted on the line at loop radius a equals 0.05 left bracket meter right bracket.

A checkbox is checked that reads show labels on graph.

A radio button is on that reads total h field.

A radio button is off that reads integrand d H.

H (0, 0, z) equals 3.535534 left bracket amperes per meter right bracket

H sub max equals H (0, 0, 0) equals 10.0 left bracket amperes per meter right bracket

R equals 0.070711 left bracket meter right bracket

Theta equals 45.0 degrees
