What is the difference between the two core loss types i.e Electrical steel and Power ferrite in Maxwell? As i am simulating a core made of ferrite, should i have to use the power ferrite type?

Ferrite is characterized by the high-frequency loss-factor Delta-H, which is related to permeability, and the common dielectric constant tangent-delta. Rarely, conductive ferrites are characterized by resistivity, rather than dielectric loss factor.
Metals, on the other hand, are characterized by resistivity only.

>core made of ferrite
Obviously, ferrite objects should be modelled as ferrites. Starting from the composition, where steel cores are made of sheets, which should be taken into account in the model. Nonconductive ferrites do not need to be layered.

The main problem I'm facing is, when i set the core loss type to power ferrite and then i insert the core loss values of my selected core its gives a message that says that, this type of core is best simulated in the electrical steel mode. Then the software select the electrical steel mode by itself. But as my core is of ferrite i know i have to simulate it in power ferrite. I don't know why it does that. Is there any chance my core loss Values are not completely accurate?

[AndyJP]

didn't you put resistivity data in conductivity cell? check it.
I have no Idea why it could offer this in other way.

Are you creating new material in the library?
If so clone an existing ferrite material and then change the data for your material accordingly.
If you are still facing a problem. Please share the screenshots of your material definition (Edit material) window and your B-H curve and core loss data details.
