Abstract
A generator having at least four coils wound around each of the winding axes, these four coils being spaced out from one another to cancel at least the first derivative up to the seventh derivative of the magnetic field generated by these coils, in parallel to the winding axis, at a central point when they are powered by the same current, and the circumference of each coil is a circle, the diameter of this circle being equal within 2% of the diameter of a circle defined by the intersection between a sphere centered on the central point and a plane, perpendicular to the winding axis of this coil, passing through this coil, the sphere being the same for all the coils wound around the same winding axis.
