Magnetic Saturation of A Piece of Steel

[Yrton]

TL;DR Summary

How can one calculate and/or measure the magnetic saturation-point of a piece of steel (steel 1018 as an example)?

Hi all.
Given a piece of a steel 1018, as an example, with a spicific mass, how can one calculate the magnetic saturation-point of that piece either using mathematical or measuring methods? I've seen graphs stating the saturation points of different ferro-magnetic materials but, I assume, it must also dependent upon the mass of the given material, in a lab experiment.
Please enlighten. Thanks. 👍

Why would the saturation depend on the mass? Maybe I am misunderstanding the question(?)
The saturation point has to do with the structure of the magnetic domains; i.e. it is a "microscopic" parameter and has nothing as such to do with the amount of material.

It is the cross section available for the magnetic path that is important.
If you double the sectional area of the steel, you can double the flux before saturation.
The tesla is the unit of magnetic flux density.
One tesla is equal to one weber per square metre.
