Description

Conventional eddy current testing has traditionally used circular pancake coils. The recent needs of high sensitivity testing have prompted the researchers to develop various kinds of test probes. The flaw detection characteristics in eddy current testing depend theoretically on the eddy current distribution induced in the test material by the probe. Thus it is quite important to know the eddy current distribution in order to detect flaws in the material on a given test condition. However, the eddy current distribution is influenced complicatedly by many factors such as the test frequency, the electromagnetic characteristics and the configurations of the test material, and the exciting coil configurations. As a result, it is not easy to find out the appropriate probe design for a given test material.
