Question about Maximal relative permeability

Noti

 

Hello,

 

can you please assist me with the maximal relative permeability ? I'm not sure which value to use, i used the value someone send me on the forum here.  For the Remanent flux density and the coercive field strength i used the values from the datasheet of vacomax, i attached the pdf document. Any advice?

 

Best regards

Hello;

 

Maximal µr must be computed from the tangent of your Magnet B(H) curve as shown in the picture bellow.

 

So you have first to extract this tangent and then you can get µr.

 

 

I hope this will help you
