Ferromagnets, permanent magnets made of iron, copper and cobalt, were first discovered by the ancient Greeks and Chinese, who called lodestones and were transformed into compasses by striking the "stones" against a steel point. These compasses were then distributed to seafaring travelers such as C. Columbus and M. Polo, and around 1600 AD it was discovered by William Gilbert that the entire Earth harnessed a gigantic magnet from within by observing the compasses and as the north needle moved towards the upper axis.[11] With the advent of magnetism, research continued to understand the mysterious force of magnetism that objects acted on. Other terms began to form such as paramagnetism: which is the explanation for the fact that some materials are attracted to the magnetic source, diamagnetism: which is where some materials repel magnetic field lines, and electromagnetism: which is where conductive materials generate magnetic fields from an induced current. For most of the millennia, classical magnetism has been employed to explain most quantifiable phenomena occurring around the world: such as the study of the Earth's magnetic field, lightning, the aurora, power lines, electric motors and other simple magnetically applied devices or activities. Classical magnetism is essentially based on the Newtonian model; including Biot–Savart law (μ0/4π qvsinθ/(r^2)), Lorentz force (F = qE + qv x B), electric field (F = qE), Coulomb law (E = k(q1q2 )/(r ^2)), Ampere's law ( ), Lenz's law Emf= -N(∆Φ/∆t), Maxwell's equations, etc., have all been formulated using electric and magnetic fields and observing how they interact with each other.[1,12] In 1819 Hans Oersted, similar to what Faraday did, discovered in the middle of a sheet of paper colliders, transformers, magnetic trains, quantum research and many other important fields/uses with Magnetism and electric current. If a room temperature superconductor were actually produced and could be widespread, there would be almost zero energy loss in power lines, earthquake resistant buildings suspended by magnets, we would be able to create quantum computers more efficiently with a better understanding of the interactions quasipariculars, better MRI, NMR, IR and mass spectrometry machines, production of space elevators, possibility of floating cars, longer and more efficient power lines, storage of energy collected from electrical storms, ability to better study laser capabilities and collectively state that superconductors would open the world a window into so many fields that it would not only improve research but also improve the world in energy consumption, use and distribution.
