31. A typical and important example is ferromagnetic ordering. 32. Like the trimeric nickel complex, this tetramer shows ferromagnetic interactions at low temperatures. 33. Enough to produce a phase change ( ferromagnetic neutron liquid / gas ? )? 34. Of the other discovered allotropes, carbon nanofoam is a ferromagnetic allotrope discovered in 1997. 35. A relatively new class of exceptionally strong ferromagnetic materials are the rare-earth magnets. 36. Ferromagnetic foreign bodies such as surgical prostheses and ferromagnetic aneurysm clips are also potential risks.37. Ferromagnetic foreign bodies such as surgical prostheses and ferromagnetic aneurysm clips are also potential risks. 38. This results in the ferromagnetic material's being magnetized, forming a permanent magnet. 39. Silicon is an important constituent of electrical steel, modifying its resistivity and ferromagnetic properties. 40. Computing the magnetic field and force exerted by ferromagnetic materials is difficult for two reasons.
