WebSep 25, 2009 · Ferrite numbers are measured using a "calibrated" gage that measure the amount of magnetic force attracting a magnet toward a sample. It is based on the principle that the "attraction" is proportional to the amount of ferrite present. It is more of a "macro" measurement and provides better consistancy from one lab to another.
