The cans are made from aluminium.

Yes.

No, if it rolls on wet it's not going to work as well.
Rusty magnets can still attract and repel other magnets like regular magnets. The presence of rust on the surface does not significantly affect the magnetic properties of the magnet itself. However, excessive rust or corrosion may weaken the overall strength of the magnet.
Magnets are used in telephones' speakers to make vibrations of air (sounds)
The Rust affects the magnet. The magnetic energy won't work as well cause it has to work thru the rust. So no, rusty magnets are not as strong as a nonrusty magnet
