A coil arrangement for contact-free guidance of a magnetic element such as an endoscopy capsule, has a number of individual coils arranged in pairs by which the components of a guidance field are generated. By arranging the individual coils to include coils corresponding to blades at an exterior of a cylindrical surface, the number of degrees of freedom required for guidance can be obtained with fewer individual coils and fewer power amplifiers to operate the coils. |
