FAQ: Hard & Soft Iron Correction for Magnetometer ...
Kovar and steel are commonly used materials that can impart soft iron errors on local magnetic fields, as shown in Figure 1 and Figure 2. Note that only distortion sources producing both hard-iron or soft-iron errors can only be compensated for if they remain fixed and rigid relative to the magnetometer as it moved or rotated through space.
Iron Loss - an overview | ScienceDirect Topics
To calculate total iron losses, we need to add up all element losses. (1.476) W l o s s = ∑ i = 1 n e W h i + W e i + W a i Where W h i is hysteresis loss of element i ; W e i is eddy current loss of element i ; W a i is anomalous current loss of element i ; and ne is number of elements.
