- n. The science and technology of ferromagnetic materials
Sorry, no etymologies found.
Sometimes, however, this is not the case and in certain compounds, known as ferromagnetics, magnetic properties subsist at a macroscopic scale and can therefore act as a magnet.
Using the new ideas of atomic physics, Heisenberg in 1928 was able to give a qualitative explanation of the aligning force occurring in ferromagnetics.
1,600 A.D. The subsequent investigation and classification of magnetic substances led to their division into three categories: the ferromagnetics or strong magnetics such as iron, cobalt and nickel; the paramagnetic or weak magnetics, including chiefly crystals and fluids; and finally the diamagnetics, with their magnetic repulsion, a property intrinsic in all substances.
