Feb 23, 2023 at 13:15 comment added Rich006 One might ask why, given that all materials are full of electrons, not all materials are attracted to magnets. It's because in most materials, the electrons are aligned randomly so that attraction and repulsion are equal. Only in certain materials do they align with some order to set up an overall magnetic field that causes a net attraction or repulsion.
