Heinrich Barkhausen was a German physicist best known for his work in the field of electronics and magnetism. He is particularly recognized for the discovery of the Barkhausen effect, which is a phenomenon observed in ferromagnetic materials. The Barkhausen effect refers to the noise produced by the sudden changes in magnetization within a material as it is exposed to an external magnetic field, which manifests as audible sounds or measurable voltage spikes.
