Yes they do!! I have just realized. The magnets well...A printer uses magnets for the buttons. The buttons are pushed, and then a magnetic signal is sent to the printer, giving it that command, and it does what you pressed.
Some water heaters may use magnets in water treatment systems to help reduce buildup of minerals in the tank and piping. This can help prevent issues such as scale buildup and increase the efficiency of the water heater. However, not all water heaters use magnets for this purpose.
Some types of microphones, like dynamic microphones, contain magnets. The magnets are typically used in the mechanism that converts sound waves into electrical signals. Other microphones, such as condenser microphones, do not use magnets in their design.
Ferro-magnets, permanent magnets, temporary magnets, and electromagnets. Ferro-magnets are magnets that are magnetic at a higher temperature than room temperature. do not quote me on that. permanent magnets are magnets that are always magnets, they are the kinds you use a lot. Temporary magnets are things that are magnetic in an extrenal magnetic field. Last but not least, electromagnets. Electromagnets are coils of wire around a cobalt, nickel, or iron. When ou run electricity through the wire, the core and wire become magnetic.
Bar magnets are already magnetized. They don't need to add wire and electricity.
Speakers and motors use magnets. Using electricity, the electromagnets create a magnetic force which reacts against the permanent magnets in these devices, thus creating motion. Magnets are used in cabinet latches to help them to stay closed. Screwdriver tips are sometimes magnetized to help hold the screw on the end or to help retrieve a dropped screw. Magnets are often used to hold things onto metal objects. Refrigerator magnets are one example. Common objects may have magnets attached to hold them onto refrigerators and other metal objects like lockers and metal cabinets.

Laser printers and ink-jet printers don't use a ribbon.
you can use magnets to separate iron from sand.
What printers use 352 ink cartriges
Laser printers use a drum and toner.
You can use Hp 92 in these HP Printers modals - HP Photosmart 7850 Printers, HP Deskjet 5440 Printers, HP PSC 1510
they use magnets to concentrate energyto them
fridge magnets speakers tv
Laser printers use toner cartridges rather than ink.
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.
Sticking things on refrigerators, some toys have magnets, there are magnets in computers and in TVs, certain doors have magnets, and most electronics have magnets.
Magnets are used everywhere. doctors use magnets for MRI's, Magnet is the the M in the RI. car plants use magnets whule moving pieces, and we use magnets to hang kids pictues on our fridges lol. hope this helped
