Embodiments include electrical conductors for signal transmission. One embodiment is a circuit board (CB). The CB has plural electrical transmission lines embedded within the CB. The transmission lines include an internal electrically conductive core surrounded by an electrically conductive plating material and an external dielectric surrounding the plating material. The core is formed of ferromagnetic material. The plating material is thinner than the core and is formed of non-ferromagnetic material.
