Induction thermography is a non‐contacting, non‐destructive evaluation method with a wide
range of applications. A deeper understanding of the detectability of cracks requires
fundamental knowledge about the induced current density distribution in the component
under test. A calculation of the current distribution provides information how much current is
flowing at which location of the component, how a crack disturbs the current density, how
much heat is produced at which location of the component, and how the heat diffuses to the …
