Intrinsic and Normal Hc??

["ahmad_m_eid" <ahmad_m_eid@xxxxxxxxx>]

Dear all 

I have a confusion when I simulate the permanent magnet in femm.

In most data sheets I have about Nd-Fe-B magnets, there are two 
values for the coercive force (Hc), intrinsic and normal values.

My question is which one is used to simulate the permanent magnet in 
femm?

any one knows sheet data reference for Nd-Fe-B magnet will be good.

thanks you all
