How do we know magnetic fields exist
WebThe magnetic domains in a magnetic material can be knocked loose, by bumping or vibrating the magnet (like when sawing it in half). If knocked loose, the domains are no longer arranged neatly, so they do not reinforce each other. If they are in a random orientation, with their fields pointing all over the place, they cancel each other out. WebDec 11, 2024 · Monopoles might exist. Because all the magnetic fields we see in the universe are generated by moving charges, you can never isolate a north and south magnetic pole (a "monopole") …
