# Thin-lamination eddy-current screening
# Scope: Thin lamination classical eddy-current loss; sinusoidal uniform flux, skin effect omitted.
# Status: illustrative worked example; engineering review pending.
# Inputs are example values. Checks are editable example requirements, not standards.

thickness = 0.3 mm
frequency = 50 Hz
peakDensity = 1 T
resistivity = 0.0000005 ohm*m
volume = 0.001 m^3

lossDensity := pi^2*thickness^2*frequency^2*peakDensity^2/(6*resistivity) [W/m^3]
loss := lossDensity*volume [W]

check eddy loss budget: loss <= 2 W

scenario alternative: thickness = 0.24 mm
