Hi Rick,
True, you can magnetize any object which is constructed from a suitable material and of a suitable geometry. I have noticed that steel sometimes becomes magnetic just from machining it e.g. drilling a hole. I often notice how drill bits become slightly magnetic and yet the material they machined was not. I also believe that magnetism can be produced in a blade just by the way in which you work the steel.
Having said that when I referred to a keris blade being magnetized I actually did not mean common magnetism but a different type of magnetism, perhaps I should have just used the word energized.
