A coil arrangement for the wireless electromagnetic transmission of energy includes a carrier which forms a main direction of extent. On the carrier element, are attached in succession in the main direction of extent and connected to one another. The carrier element comprises a ferrite material and at least one desired parting location which is designed as a perforation and/or notch arrangement. The coil arrangement can be easily adapted in a flexible way to a rotatable component and attached thereto. This makes easy wireless electromagnetic transmission of energy possible.
