The simple answer is no, mass does not affect electromagnetic forces: only the position and movement of charges do. See the Lorentz force F = q ( E + v × B). Note that mass is nowhere to be found in this equation.
WebThe textbook answer I seem to find everywhere is that they are a way to represent field strength and direction, they flow from north to south and the strength of the magnetic field is represented by the density of the lines in a given area. Sure, that makes sense. However, my question arises when I physically see lines of flux when I scatter iron filings around a … Web28 dec. 2024 · The magnetic field forms packets of energy that prevent the ozone layer from losing carbon dioxide. You can observe this by pouring iron filings, small powder-like pieces of iron, in the presence of a magnetic. Place a magnet under a piece of paper or light sheet of cloth. Pour the iron filings and observe the shapes and formations that they …

WebIn classical electromagnetism, magnetic vector potential (often called A) is the vector quantity defined so that its curl is equal to the magnetic field: =. Together with the …
WebMagnetic fields are relativistic electric fields (ie. the creation of an electric field due to space contraction from moving charges), but this was not known until Einstein's theory of relativity. Before relativity was discovered, magnetic fields were known to be generated by current (ie. moving charges) or changing electric fields. Comment phishing illustrationWebMagnetic fields occur whenever charge is in motion. As more charge is put in more motion, the strength of a magnetic field increases. Magnetism and magnetic fields are one aspect of the electromagnetic force, one of the four fundamental forces of nature. We need to simplify this setup. Picture a clock.
