Abstract
A device for generating a random electric signal, including an input duct, an output duct, a generator of magnetic particles generating magnetic particles in the input duct, a diffusion chamber connected to the input duct and the output duct, wherein the diffusion chamber is designed to diffuse the generated magnetic particles, a displacement unit for displacement of the generated magnetic particles towards the diffusion chamber, and a converter that is designed to generate an electrical signal proportional to a characteristic, wherein the characteristic is the particle density in the diffusion chamber or the passage of magnetic particles at a predetermined location of an output duct connected to the diffusion chamber.
