Hi, I am pretty new in the area of magnetism. Please pardon me for some questions that might be pretty fundamental and basic here.

I am trying to understand the difference between magnetic moment and magnetization. I thought I understood magnetization as the degree to which a magnet is magnetised, thus the amount of field present within it, as in the self induced magnetic field within the magnet itself. However, I am unsure as to how the magnetization affect the external of the permanent magnet... and then I thought magnetic moment would be the moment (i.e. the torque) onto the permanent magnet giving that amount of magnetization within it, so the magnetic moment and be related somewhat to the magnetization

=S sorry, I hope I am not making this sound too confusing as I am pretty much confused myself.

I would need to clarify my doubts in this as I need to find out the magnetization for a cylindrical NdFeB for a dynamic equation that I am working on. I understand that the NdFeB, a ferromagnetic material has a non-linear B-H relationship, thus it doesn't have a constant magnetization value. Nonetheless, is there anyway I could find out? I would like to assume that the region of operation I will work on is linear as the range of current supply is small (i.e. ~ +/-5A) but I am not sure if that makes sense.

I look forward to any advice and suggestions =)

Thank you!
