Abstract
A magnet winding in a air coil configuration with windings made from conducting elements which surrounds a magnetic field axis and is wound in at least two layers with at least one layer transition, is characterized in that, in an angular region about the magnetic field axis which includes a layer transition, the radial separation from the magnetic field axis of at least the radially innermost winding of a respective layer is less than that in the other angular region. In this manner, it is, to a large extent, possible to compensate for the magnetic field breach resulting from the "thinning" of the effective active conducting elements of the innermost winding in the region of the layer transition.

Magnet winding comprising windings made from conducting elements forming a coil having a longitudinal axis and surrounding a magnetic field axis which is coincidental with the coil longitudinal axis, said windings being wound in at least two layers separated along the longitudinal axis, said layers being interconnected by at least one layer transition, said windings having an angular region about the magnetic field axis which includes the layer transition, and a radial separation from the magnetic field axis of at least a radially innermost winding of one respective layer is less than that of a radial separation of the innermost winding in another angular region, the radial separation of at least a radially innermost winding of the respective layer from the magnetic field axis, at a middle of the angular region being less than that outside of the angular region by about half a radial extent of the conducting element.
