This paper presents a primary study and its results of the thermo-electric field in a steel strip with multiple cracks under the electric current. As a result, the hot spot exists at the crack tip due to the Joule heating effect. When the gap between two cracks is relatively small, the hot spots at the crack tips may not be obvious. It may disturb the crack detection.
