Barkhausen Noise Analysis
Barkhausen noise analysis is a non-destructive method involving the measurement of a noise like signal induced in a ferromagnetic material by an applied magnetic field.
There are two main characteristics that will directly affect the intensity of the Barkhausen noise signal: hardness and stress.
Barkhausen Noise Analysis (BNA)
Barkhausen noise analysis (BNA) also referred to as the micromagnetic method is based on a concept of inductive measurement of a noise-like signal, generated when a magnetic field is applied to a ferromagnetic sample.
The nature of Barkhausen noise was explained already in 1919 by Prof. Heinrich Barkhausen. However, the method drew the attention for industrial applications in the beginning of the 1980s by Dr. Seppo Tiitto and Dr. Kristi Tiitto who are also the founders of Stresstech. Today, it is a recognized non-destructive method for materials characterization and heat treatment defect testing.
