Lodestone, or magnetic stone with iron, have been known to exist in India for several thousand years, and was very early used for the first compasses, as it, when put on water will turn so it points north south.
Does anyone know if it was used for weapons?
Maybe the content of iron was too little, or maybe it was too soft.
What is the reason that we hear so much about wootz and so little about the magnetic lodestone?
When you forge you will need heat and a hammer, and when you cast you will need heat – both heat and hammering kills magnetism. So whatever magnetism a dagger or a sword have, it must have been made after the weapon was finished.
I have a tulwar where the blade is magnetic on the middle but fades out, it can pull the needle from N to ESE or about 130 degrees, but the hilt can pull the needle all the way around
It is known that cast iron is easier to magnetize than forged iron, due to the rough structure of the iron, but it is also known, that cast iron looses the magnetism easier than forged iron. The finer the structure is the harder it is to magnetise the blade, but the longer it will stay magnetised. I don’t know how long time it would take, for a wootz blade to loose its magnetism, or for a cast item for that matter, but if a blade has been magnetised from the start, and it is, maybe two hundred years old, there is reason to believe that some of the magnetism has been lost – but how much?
Why make a blade magnetic, and a magnetic hilt is an even bigger puzzle. The only answer I can come up with at the moment is, that only few knew how to magnetise, and that a magnetised blade was magical. But is that the right answer?
Does anyone know the answer, and those of you who have magnetic blades, are this blade of high or of average quality?
On this page you can read about magnetism, it is rather interesting. http://www.newi.ac.uk/BUCKLEYC/magnet.htm
And on this one too.
