what is a magnetic polisher?
WRT stainless steel magnetic properties, there are 2 crystal
structures involved, austenite and ferrite.
austenite (occurs in pure FE at high temperatures) is face centered
cubic and non-ferromagnetic ferrice (occurs in pure FE at room
temperatures) is body centred cubic and ferromagnetic.

Stainless steel is an alloy with significant amounts of Cr and Ni Cr
is a ferrite promotor and Ni is an austenite promotor the balance
between the two determines what crystal structure and hence what
magnetic properties the steel has at room temperatures…
