I was standing at work, and the tought struck me.. How is magnets mined? Because it would require mining equipment to move trought the rock. As far as i know most of this equipment is made out of iron. Wouldent that mean that the catepilar get,s stuck towards the rock wall?
So how do they get to the magnets? Plastic catepillars?
