They don't. Magnets have no impact on compact discs, since they don't work by magnetism.
Water, wood, and plastic are all non-magnetic. Magnets will not attract them.
That depends on the strength of the magnet and thickness of the glass.A regular magnet may work through a thin piece of glass, however a weak magnet will not work through a thick piece of glass.
Because you know how magnets work.
Well, rusty magnets do not work as well as a normal magnet. But they can work. And yes try can repel but if you use rusty magnets, it won't work as well. I hope this helped! :)
electronic magnets as they work with electricity produced
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
magnets... how do they work?
