The models provided in Flux for the B(H) equivalent dependencies are presented in the following table.
| Model | Hypothesis | Equivalent B(H) curve |
|---|
| Non-modified curve* | -
| Real B(H) |
| Sinusoidal induction | B sinusoid B = Bmsinωt | This model is based on the following energetic equivalence: 
This model is more adapted for the simulation of devices with a voltage supply. |
| Sinusoidal H field | H sinusoid H = Hmsinωt | This model is based on the following energetic equivalence: 
This model is more adapted for the simulation of devices with a current supply. |
| Mixed | -
| This model is the linear combination of the two preceding ones: Beq=αBeqBsin+(1-α)BeqHsin Heq=αHeqBsin+(1-α)HeqHsin where α is a weighting coefficient chosen empirically in the interval [0, 1] |
| Average of ν over a period | B sinusoid B = Bmsinωt | This model relies on an equivalent reluctivity νeq calculated by getting the average of reluctivity over a period of time: 
It is much less precise than the others for high values of magnetic flux density, as it does not observe the asymptote of µ0 slope |
