Indeed.
Despite my own work in making knives and other blacksmithing things, where I LITERALLY have a magnet on my anvil so I can test for when the steel hits it's austenitic temp, I somehow managed to forget the iron will go non magnetic...
So yeah. Thanks for the reminder!
In my defense I haven't made any knives since moving a year ago...
However, this is aluminum I think? I'm not entirely sure how magnetism works with lenzs law and if there's a temperature it stops working...
Unfortunately, they very much do.
And they don't understand who the good guys are in 40k either (it's no one. Except maybe tyranids acting at an instinctual level)
