the magnet gets weaker
Copper does not rust. It can however be eaten by low PH water and Chlorine.
it attracts
Usually nothing.
When some pieces of plastics are brought near the magnet, they will get attracted.
Nothing happens, except that now you have two magnets. The poles of a magnet are not actually localized at the two ends of the magnet but are inherent to the magnetic properties of the magnet. As the magnetic properties are not altered by a modification of the magnet such as cutting it in half, there will be no effect on the poles of the magnet.
no not really
A Black Magnet
A magnet Will pick up rust flakes And a magnet can get rusty looking however I don't think you can get much magnetism out of a piece of 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
when rust happens iron comes into contact with water and oxygen and rust forms
A strong magnet or electromagnet can be used to hold the iron oxide(rust) in place as the water is poured off. Care should be taken to bring all of the rust near the magnet in order to collect it all.
no rust mostly happens to metals and diamonds are not metal
Put it in Salt Water then, let it out to dry. After that, you repeat it a couple of times.
Move towards the U magnet so that the poles attach.
the nail goes to the magnet
Nothing happens, it does not attract.
