Car magnets doesn't cause rust.
Magnets are attracted to anything with iron in it. Rust is Iron Oxide, so yes!
If they are an alloy, they will eventually rust.
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
How long will it t take a quarter to rust in fresh water
a long time
It depends on the quality of the nail. If it is painted it Amy take long to rust. In general it may take a month or so for the nail to rust.
Refrigerator magnets can rust if they are exposed to moisture or high humidity. The metal components in the magnet can oxidize when in contact with water or moisture, leading to the formation of rust. To prevent rusting, it's important to keep magnets dry and clean.

Rust, which is iron oxide, is not magnetic because the oxygen atoms in rust disrupt the alignment of iron atoms. This disruption prevents the iron atoms from forming a magnetic field, so rust is not attracted to magnets.
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.
