Is Gold Magnetic? - UMD

2019-2-2 · The electric current has its own magnetic field It is this magnetic field that is interacting with the moving magnet. So while silver isn’t magnetic it can interact with magnets if they are moving. If you had a silver pipe you could drop the magnet down the pipe and it would fall very slowly. This also works with aluminum and copper.
