WebMagnetizing an object clearly requires energy. It is now placed into an ordered state from which there are many other possibilities. Therefore, it has moved from a state of relative … Many materials have unpaired electron spins, and the majority of these materials are paramagnetic. When the spins interact with each other in such a way that the spins align spontaneously, the materials are called ferromagnetic (what is often loosely termed as magnetic). Because of the way their regular crystalline atomic structure causes their spins to interact, some metals are ferro…
