Before the discovery of the neodymium magnet, the strongest permanent magnet was the samarium–cobalt magnet, which was based on the Sm 2 Co 17 intermetallic phase. However, samarium is expensive ...

The world's strongest permanent magnets made of neodymium measure around 1.4‑1.6 teslas. Niron’s Clean Earth iron nitride permanent magnets peg the meter at 2.4 teslas. Niron Clean Earth ...

and it may soon be possible to build permanent magnets as strong as neodymium magnets, but without any rare earth metals. In fact, the only thing needed to make them is iron and nitrogen ...

In a laboratory, the repulsion of water by really strong magnets (more powerful than the neodymium ones here) has even been used to make small animals levitate. Please don't annoy any pets or wild ...

Put your rod away and search in outdoor waters for ferromagnetic objects available to pull with a strong neodymium magnet. Find rare and valuable items, restore them, and sell! Advertisement All ...

The magnetic fields of neodymium magnets can be extremely strong since they are able to be made to be very large. Due to their strong magnetic field, it is nearly impossible to attach a large magnet ...
