The way a magnet works is they have magnetic Fields from the north and south pole.
ask the mormons
No, there are no magnets in a normal mechanical piano.
Yes, they do, but their affect is minimal. Magnets with their magnet fields affect inductors profoundly, but don't do to much to capacitors.
it will lose its magnetism OR it will get weaker
YES! Rare Earth, and electromagnets. Any coil is a magnet once electricity is added. Speakers use them, the receiver uses them and the amplifier uses magnets as well as the power supply and any noise chokes.
Electric Guitars,
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
no
Yes.
MIRACLES
Yes.
yes
Like magnets.
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
