    Magnetic core, preferably for Pupin's coils.
 2. Earth core
 If, as shown in the figure, the core is composed of four ring-shaped disks of the same thickness,

 <Desc / Clms Page number 2>

The effective permeability achieved here (J. = 51 can practically not be achieved with any of the previously known methods while observing the limits of stability and losses.
