I need to use Y30BH magnet in ansys maxwell. For this in the materials I found the BH curve of the magnet. May i know this curve is plotted for which temperature? Do we have other ferrite magnets to use at different temperatures

Hello,
The B-H curves are created for simulation under no temperature modification. Meaning that data is taken from multiple references such as material datasheets and a B - H curve is created, but a change in temperature does not change this B-H curve. In order to make the material properties temperature dependent, one would have to add a thermal modifier on the material properties. This is done by checkin the "Thermal Modifier" check box on the material properties. The thermal modifier could be a simple gain or a temperature dependent dataset.

Hello sir,

     I am very much thankful for the information. In Ansys maxwell document i found that the BH curves for Y30BH are obtained by interpolation as follows. Can you please clarify this
