Simple explanation of magnetism
WebbExperiments with magnetism or also known as magnets can be found throughout history in the form of hypotheses made to carry out tests for important discoveries that we can find nowadays. For example, the magnetism of the earth. Webb1 a : a class of physical phenomena that include the attraction for iron observed in lodestone and a magnet, are inseparably associated with moving electricity, are exhibited by both magnets and electric currents, and are characterized by fields of force b : a science that deals with magnetic phenomena 2 : an ability to attract or charm Synonyms

Webb7 juli 2024 · The formal name for the physics equation that defines the behavior of an induced electromagnetic field from the magnetic flux (change in a magnetic field) is Faraday's law of electromagnetic induction. The process of electromagnetic induction works in reverse as well, so that a moving electrical charge generates a magnetic field. While heuristic explanations based on classical physics can be formulated, diamagnetism, paramagnetism and ferromagnetism can be fully explained only using quantum theory. A successful model was developed already in 1927, by Walter Heitler and Fritz London, who derived, quantum-mechanically, how hydrogen molecules are formed from hydrogen atoms, i.e. from the atomic hydrogen orbitals and centered at the nuclei A and B, see below. That this leads to magne…
