Abstract
The invention relates to a coil system which includes a plurality of series-connected coils ( ) which are provided with parallel coil turn configurations ( ) which are insulated from one another and connected to those of the neighboring coil ( ) so as to form conductive paths ( ) which span coils. Conventional coil systems have the drawback of lack of flexibility in respect of the numbers of turns. It is an object of the invention to provide a coil system which does not have an integer effective number of turns and nevertheless satisfies the requirements imposed as regards the quality of the magnetic field. In accordance with the invention it is proposed that the individual coils ( ) are provided with at least two groups of coil turn configurations ( ) whose numbers of turns deviate from one another and which are connected to the coil turn configurations ( ) of the respective neighboring coil ( ) in such a manner that the summed number of turns of each conductive path ( ) is the same. An advantage is offered by the freedom achieved as regards the choice of the number of turns of the coils.
