Magnetic attraction occurs due to the effect of magnetic fields on electrical currents. An electric current would be the flow of electric charge (positive or negative depending on the amount of electrons present). A magnetic field is produced by moving electrical charges to effect other charges (basically).
Because you know how magnets work.
electronic magnets as they work with electricity produced
Magnets
Like magnets.
Yes.
no
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
magnets... how do they work?
Cold. If magnets get overheated, they can cease to work all-together.
No, bulbs do not make use of magnets to work. Light bulbs function by passing electricity through a filament, which then emits light and heat. Magnets are not involved in the process of generating light in bulbs.
