I remember back in the 1980's a writer for Live Steam magazine, Chas. O C Darling, mentioned he hung a bar magnet from a string in his shop. This was used to test the attraction, or lack of it, on red hot bars of steel, for the same purpose of knowing when it was ready for quenching. It's an old and very useful technique. Mr Hiraoka knows all the tricks!
