Is Silver Magnetic - University Of Maryland

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.

Magnetite - Wikipedia

Magnetite is a rock mineral and one of the main iron ores, with the chemical formula Fe 3 O 4.It is one of the oxides of iron, and is ferrimagnetic; it is attracted to a magnet and can be magnetized to become a permanent magnet itself. It is the most magnetic of all the naturally-occurring minerals on Earth. Naturally-magnetized pieces of magnetite, called lodestone, will attract small pieces ...
