Acceptance Level		Depth of penetration decreases as the frequency increases
Conductivity		A level above or below a specific criteria in contrast to rejection level
Coupling		Probe for testing inside an object "Bobbin"
Depth Of Penitration		Time displacement between two sign waves of the same frequency
Encircling Coils		Intrinsic property of a material to carry electric current (MS/m) ( I.A.C.S )
Fill Factor		Coils that surround the object being tested
I A C S		Any "non-relevant" interference signal
ID Coil		Ratio of the cross-sectional area
Pemiability		Maximum "permeability" in the test object
Phase Angle		A current in one coil causes voltage in the other
Threshold Level		International Annealed Copper Standard
Transducer		Dynamic relations between magnetic induction and magnetizing force
Skin Effect		Intrument that only registers changes within a set magnitude
Probe Coil		Probe that is placed ON test object
Noise		Magnetic strength of penetration from 100% - 5% Surface to 3rd
Magnetic Saturation		Converts electrical energy into magnetic energy
