| Mar 26, 2020 at 15:01 | comment | added | creillyucla | I tried this with a nail and four fridge magnet stuck end-to-end and it seems to agree with your procedure. That is, the nail will "snap" to the poles when moved around the magnet, but the magnet will stick anywhere on the nail. How do I know this is not an accident of the particular geometry of the nail and magnet? The induced dipole moment will be strong for different nail orientations, so how do we know that a geometry geometry will not lead to "snapping" of the magnet to the locations which optimize the induced dipole moment in the non-magnet? | |
