Magnetic Fields of Coils
The magnetic field inside a solenoid is measured in the radial and axial directions. The magnetic field of Helmholtz coils is measured as a function of distance along the perpendicular axis.

This plot shows the magnetic field strength along the axis of Helmholtz coils for three different coil separations. The green data is for coils with the proper separation (the coil radius); the red data is for the coils tooclose together; and the blue datais for the coils too far apart. The green curve is the measured magnetic field vs. distance along the perpendicular axis of a single coil. The red theoretical curve is plotted from an equation.
