How to calculate the induced magnetic moment of steel from an applied field

[Rizer]

Excuse me, can anyone teach me how to calculate the induced magnetic moment of steel, given the applied magnetic field?

Can you give us the background for this question ? Is it for a class - if so, what grade/level ?

 

[Rizer]

Thx for answreing.
I think this is a University question...

That's not enough because the answer varies depending on what approach you take on the problem. Is this in context of classical electrodynamics or condensed matter physics? Intro or advanced(graduate level)?

 

[Rizer]

It is only at introductory level.

Please concern it as easy as possible, classical electrodynamics I think.

Typically, you can estimate the magnetization from the susceptibility. But depending on the material (kind of steel) the hysteresis might ne large enough that you'd want to refer to a magnetization curve to determine the induced magnetization at a given field.
