Iron nitride permanent magnets made with DIY ball mill and tested with DIY magnetometer

I show the process of making iron nitride permanent magnets by ball milling ammonium nitrate and iron powder. Some researchers think that the theoretical performance limit of iron nitride magnets is higher than neodymium iron boron, but so far, no one has been able to show this.
