Magnetite
It's not as easy as it looks, you have two types, one is magnetized and one isn't, I'm guessing Magnetized Magnetite is what we want, and i figured that you want it naturally magnetized rather then getting it magnetized yourself.
creating a one pole magnet, hmmmm, doesn't seem right, i mean everything has 2 poles, the planet has 2 poles, how can a magnet have one pole, how is it even a magnet if thats the case? abit confused, maybe theres more to it then just that.
I have a miner keeping a eye out for me that is currently working on a conveyor belt that he sorts threw the ores that come threw, he is the one that told me there are two different types of magnetite, and it's rare for him to come across the Magnetized type.
hmmmm,
Hopefully he comes across some, i need to see if this is right!
Peace be with you all.
