Abstract

A directly cooled magnetic coil, particularly a gradient coil for a magnetic resonance apparatus, has the conductors forming the windings which are provided with an inner cooling channel for conducting a cooling fluid therethrough, and the conductors are fashioned as profiled segment conductors whose individual profiled segments surround a cooling tube. The cooling tube is composed of material that is not electrically conductive, or is only slightly electrically conductive, particularly a flexible plastic.
