Building a precision Maxwell coil

In order to calibrate a magnetometer, a known uniform magnetic field may be used. The most common way for creating uniform magnetic fields, is a pair of Helmholtz coils. In a previous video I built a 3 axis Helmholtz coil:    • Building a magnetometer desktop calibrator...   . The idea worked, but the intensity of the generated field per axis was not known precisely. It would be nice to have a larger volume of uniform magnetic field with a precisely known intensity. A better alternative to Helmholtz coils is the Maxwell coil. Let us build one.
