Abstract
Various embodiments include apparatus and methods to inspect casing defects in a pipe such as a casing associated with a drilling operation. Electrical connectors contacting the inside wall of the pipe can be used to generate a current in the pipe. Magnetic fields correlated to an anomaly or anomalies that alter the current can be sensed to identify the presence of the anomaly or anomalies. Additional apparatus, systems, and methods are disclosed.
