Coil e.g. rectangular coil, producing method for generating spatially defined, controllable magnetic field, involves rolling flexible, electrical insulating substrate on which conductor is superimposed or in which conductor is placed

摘要

The method involves rolling a flexible, electrical insulating substrate (3) on which a conductor (2) is superimposed or in which the conductor is placed, such that the conductor forms a three dimensional conductor structure. A single layer is superimposed on a side of the flexible, electrical insulating substrate, before the rolling of the conductor. A flat coil is generated on a layer of the substrate. The flat coil is executed as a spiral coil (8), a meander coil or a helix coil with a magnetic conductor.
