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… Web30 mrt. 2024 · Electromagnetism is the relationship between electricity and magnetism, and it’s the foundation of electric motors, as well as generators and transformers. Michael Faraday discovered the relationship between magnetic fields and electricity in the 1830s. One of his most important contributions to the field is Faraday's Law of Electromagnetic ... government shutdown 2021 upd
