'Magnetics Design 5 - Inductor and Flyback Transformer …

Stray Flux. Another problem that must be faced is stray flux, associated with energy stored in a fringing field outside the gap. Stray flux couples noise and EMI to the external circuit and to the out-side world. This stray energy also increases the in-ductance b(!yond its intended value by an amount that is difficult to predict.

1 Basic in EMC and Power Quality - Schaffner

Common-mode noise results from stray capacitances in a system, often occurring between semiconductors and heat sinks. It is more often found in the higher frequency range. When we look at the measurements later, we will see that the result of the measurement does not make the differentiation between the two types of noise.
