Hello
I just one simple question: when we add a BH-**curve** for a ferrite material in HFSS, the H in the BH-**curve** file should be the internal H values ?or the external H values?
Thank you
Sincerely

Hello, A nice measurement is the low frequency BH **curve**. The basic setup is relatively simple, but you need some math to convert the measured properties back towards magnetic field properties.
You can find an example measurement setup at:
If your Digital Oscilloscope has int

Hello, I am trying to compare BH **curve**s on the 43 material and the 3R1 mterial.
In the piscture the 43 **curve** is shown on the left and the 3R1 on the right.
I am a bit confused of the graph units, could you notify me which one has a more square BH **curve** that sharply bends at the saturation points?
A rough comparison of the bending (...)

Hi,
I am working to model a flux gate (it is nothing but inductor with iron core, whoch shows differrent behaviour at differrent external magnatic field).
What I am trying to achieve is to realise a mathmatical model which can take external magantic field as input and use BH **curve** to change the behaviour of flux gate. Any help would be highily a

Not really. Peak to peak swing would impact the loss. Also swing would impact the area of BH loop. Also there would be some eddy current loss, but it's contribution would be much less. Also it is true that area of BH loop represent the Hysteresis loss
The area inside the B-H **curve** represents lost power. It takes energy to move around the B-H c

hi,
Can anybody help me to plot a dynamic hysteresis **curve** either PSPICE or Matlab/simulink.Some of the parameters keep on changing ( I am using jiles atherton model parameters in an iterative way, so i need a bh **curve** which is dynamic)
It would be great if you reply soon.
Thanks

Hi Friends,
What is the relaationship between the BH **curve** and the **curve** between Induced EMF and Field current.

I think that BH **curve** is usefull when your are going to work near to core saturation.
Normally, that **curve**, or its characteristic points, are given for high power cores.

Doubts on determining the permeability from BH **curve**. The formula of permeability is
? = B/H
... which is NOT given by the SLOPE of BH **curve**, right?
Hi,
I attached your B/H picture slightly edited with showing the CHANGE in H and the corresponding CHANGE in B, so using my numbers in the picture the permeability o

You have to watch out for the DC current rating. When filtering DC you need to look for the series resistance which will cause heating and voltage drop. You also have to look for the reduction of the inductance (when there is some core material other than air or an insulating support) from being biased of the center of the BH **curve** by the DC curr
