Eddy current inspection may be learned directly on a notebook, tablet or smartphone. The students work with their beloved devices they know best. This makes the contact to a complicated inspection method not only less painful but even creates a certain enthusiasm.
The paper presents interactive eddy current tools for learning and teaching. It aims to help beginners to understand this non-destructive inspection method. The tools work with up-to-date Windows notebooks, Android smartphones and tablets. All typical tasks like sorting, crack detection, hidden defect and corrosion inspection and even dynamic inspection using low and high pass filtering and signal indication in XY- and Yt-mode may be learned using reference pieces. For teachers and trainers the tools offer best opportunities to demonstrate an eddy current instrument using data projectors.
Not only single probes but also probe arrays may be plugged directly to a Windows notebook allowing simple eddy current imaging. An engraved aluminium sheet is used as reference piece to be read from both sides.
