Magnetics and inductive devices

Magnetic-circuit approximations with calibrated material data.

turns, current, length, core assumptions → field estimate, approximation limits

path lengths, areas, permeability curves, turns/current → flux, MMF, gap drop

gap field, pole area, leakage/fringing assumptions → idealized attraction force

turns, magnetic path, gap, material → inductance estimate, saturation screening

inductance, current, core data → energy, gap-energy estimate

waveform, frequency, core area, flux limit → minimum turns, flux swing, turns ratio

turns, mean length, wire section, parallel paths, temperature → resistance, fill fraction, loss

flux waveform, frequency, volume, fitted loss coefficients → conditional core loss

thickness, resistivity, frequency, sinusoidal flux → classical loss estimate, limits

frequency, resistivity, permeability → skin depth, conductor-size comparison
