why does steel does not get magnetised like sofs iron

answered-by-expert Expert Answer
Steel in natural form has magnetic permeability (the degree of magnetic response) close to 1. Hence, it is non-magnetic under normal conditions.
However, if ferrite components are mixed more in steel, then its magnetic permeability increases and it can be magnetised to certain extent.
Also, some heat or cold tretment can change the permeability of steel and it can be magnetised to a larger extent.
