2. Theoretical aspects of the method

Magnetic particle testing involves complex magnetic phenomena which, to be properly presented, would require explanations that go beyond the somewhat simplified presentation given in this chapter. The aim of this presentation is to give readers a clear understanding of the important aspects of the magnetic particle testing method, without entering into abstract theoretical demonstrations that are too far removed from the method itself.

2.1 Physical quantities and units

We need to distinguish between two different magnetic quantities which do not have the same meaning: magnetic field and magnetic flux density (figure
