Material manufacturers generally supply non-saturation magnetic characteristics for different magnetic devices, but some applications require these characteristics during high saturation conditions. Two common procedures for finding these characteristics are Vibrating Sample Magnetometry (VSM), which requires complex and expensive laboratory equipment, and IEEE Standard 393-1991, which is simple and relatively inexpensive, but not as accurate as VSM.

Purdue University researchers have developed a new test apparatus and computational procedure for characterizing highly permeable magnetic materials under both unsaturated and saturated conditions. The method is experimentally simple, inexpensive, and more accurate than IEEE Standard 393-1991.

Advantages:
-Simple and inexpensive
-More accurate than IEEE Standard 393-1991

Potential Applications:
-Materials
-Manufacturing
-Instrumentation
