The present invention is directed to a system for generating a healthy energy vortex within a space through an earthing effect. The system may comprise a plurality of copper-clad earthing poles encompassing a perimeter of an area. Each earthing pole of the plurality of earthing poles may be completely submerged underground, may contact a plurality of healthy negative ions underground, and may not contact a separate structure. Each adjacent pair of earthing poles may be separated by a distance suitable for generating the healthy energy vortex through the earthing effect. Each earthing pole may further comprise a cap of grounding enhancement material and a wire connecting the earthing pole to adjacent earthing poles. The system may further comprise a plurality of magnet pairs disposed underground outside of the perimeter of the area encompassed by the plurality of earthing poles.

Device for protection against electric and/or magnetic fields, in particular electromagnetic fields, comprising a switch and a field coupled with the switch, wherein the switch has at least two protection elements, wherein a protection element comprises at least one film capacitor and at least one diode. The switch emits nature-like wave packets, generated by the diodes and capacitors by spontaneous discharges into the environment and the electric field of the power line, whereby the signals correspond to the electric discharges of AIS. A method for operating such a device is also provided.

Embodiments herein describe a variable inductor containing a capillary. The capillary includes an eutectic conductive liquid (e.g., EGaIn) containing suspended magnetic particles and an electrolyte (e.g., NaOH). In one embodiment, the variable inductor has a pair of electrodes (e.g., negative and positive electrodes) at the respective ends of the capillary to seal the eutectic conductive liquid and the electrolyte. The variable inductor also includes an inductor coil disposed around the capillary, and the inductor coil is connected to a circuit and provides inductance for the connected circuit. Using a DC voltage between the pair of electrodes, the eutectic conductive liquid can extend inside the capillary, which in turn, causes the variable inductor to have a desired inductance.
