The Magnetic Pie Field Indicator, also known as a pie gauge, is a device used as an aid in determining the direction of magnetic field for detection of discontinuities in ferrous materials.

It is an octagon shaped piece made with a low retentive steel surface having eight bonded slices, similar to pieces of pie.

The octagon shaped piece is mounted on a handle so the inspector can place it on the part in the area being magnetized.
