A rod-shaped magnetic core element, having a first end with a spherical or cylindrical recess or a spherical or cylindrical connecting protrusion, and a second end with a spherical or cylindrical recess or a spherical or cylindrical connecting protrusion so that a bent connection of at least two magnetic core elements is variably adjustable. Magnetic core elements comprising spherical or cylindrical magnetic core ends of this type allow a nearly gap-free construction with little magnetic leakage due to slightly larger end surfaces in comparison with ferrite rods having beveled plane end section surfaces. The enlarged end surface of the spherical surface advantageously allows a more stable connection of individual magnetic core elements without adhesive bonding. This allows the construction of flexible, multiple-member and inexpensive rod core coils and antennae. |
