A break in the continuity of a conductor affects its magnetic field and resistance, as a continuous circuit is essential for electric current flow, which generates a magnetic field. Resistance is influenced by the effective cross-sectional area of the conductor, and microscopic fractures can further complicate this. Detection methods for such fractures include reflectometry and measuring the conductor's resistance. Reflectometry can be effective even for low-frequency radiation, although the discussion primarily references x-ray reflectometry. Understanding these concepts is crucial for analyzing conductor performance in electrical applications.
