If you stack Nib disks, one on top of the other as the disks get successivley smaller as well as stacking more on the under side, making sure that they all line up on the same axis you will have made a sphere with circular steps in it, top positive and the opposite pole on the other end. Now you'll have a very very very much stronger flux filed than what you would have imagined. PLEASE BE CAREFULL, wear eye protection and be ready for a pinch or blood blisters. Then, take your assembley and dip it into the smallest ferrous granuals as possible, remove and your done. Try stacking various configurations to come up with what your looking for, Good luck. I haven't been able to take mine apart, it's that strong. My original intention for this was to make an exterior magnetic field, It was succesfull.
