100 Years of Barkhausen Noise

Did you know that Barkhausen noise turned 100 years this year? Barkhausen noise was discovered in 1919 by a German physicist named Heinrich Barkhausen. Industrial applications for the Barkhausen method began in 1980 and today it is a widely recognized non-destructive testing method for grinding burn detection, material characterization, and heat treatment defect testing. Follow the timeline and see what has happened over the last 100 years.

From science to industry

Timeline of the history of Barkhausen Noise

Barkhausen noise in science

Barkhausen noise analysis is a non-destructive testing method involving the measurement of a noise-like signal induced in a ferromagnetic material by an applied magnetic field. The phenomenon is studied at universities and research centers around the world to evaluate the mechanical and structural characteristics of ferromagnetic materials.

Barkhausen noise in industry

In the 1980s, the first Barkhausen noise applications were used in steel rolling mills and crankshaft manufacturers who were testing for grinding burn damage from the manufacturing process. Today, the Barkhausen noise method is used in automotive, aerospace, energy, and other manufacturing industries as well as universities and research institutes.
