Uniformity of the magnetic field of a system of round and square conductors carrying current

A comparison was made of the magnetic field of a system of two coaxial equivalent round and square conductors with the current in the working area of the systems - the space between the conductors. It is shown that a minimum magnetic field inhomogeneity of the order of one percent is achieved both along the axis of symmetry and in the center of the systems in a plane perpendicular to the axis. It has been established that the uniformity of the magnetic field in the working space of systems of round and square conductors carrying current is approximately the same.
