Yes.
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.
Super magnets are used to help produce sound in speakers. They also help pick up vibrations in electric and bass guitars. These magnets come in many different forms.
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.
Magnets may not always attract if the opposite ends are not towards each other. For a magnet to work, the possitive end has to attract the negative end and visa versa. Failure of these ends meeting means the magnets will not work.
well it uses magnets duhhh.... :P
Every machine with a motor has a magnet. If you plug it in, it has a magnet. If you put in batteries or recharge it, it has a magnet. An automatic pencil sharpener uses magnets. A computer printer uses magnets. A refrigerator motor uses magnets. An electric razor uses magnets. A fan uses magnets. Hair cutters use magnets. Nose clippers use magnets. Look around your room and see what else uses a motor.
A construction crane uses a large hook, or a wrecking ball.

Yes, magnets would still work in the absence of gravity. The force generated by magnets, known as the magnetic force, would still attract or repel objects based on their polarity, regardless of the presence of gravity.
Because you know how magnets work.
magnets are used in class,at home or even in the loo!Everybody uses magnets all the time.You might be using one now,for all we know.
