Relative Reluctances in Thick Aluminum Samples
The effects of sample thicknesses, frequencies, and values of lift-off on real and imaginary reluctances for a modified ac magnetic bridge were found for aluminum. Aluminum test samples with thicknesses varying between 0.406 and 6.35 millimeters were scanned at values of lift-off ranging from 0.1 to 0.38 millimeters and at frequencies between 200 and 5000 Hz.
