The Pie Gauge is a tool for quickly verifying the direction of magnetic flux on a surface.  It is made from eight ferrous segments, braised into a single piece, providing a star pattern of nonferrous discontinuities.  Typically used with dry powders for yoke inspection, the Pie Gauge can be held at any angle and will generate indications perpendicular to the direction of the magnetic flux. A similar test gauge, the Berthold Penetrameter, uses four instead of eight ferrous sections and is commonly used in Europe.
