Name two common devices that uses electromagnets?
The answer is TV and door Bell !
What are some uses of electromagnets?
In general, electromagnets are used to move things; whether it be ultra small things like molecules or super large things like locomotives or cruise ships. MRI systems use electromagnets to "move" or at least change the polarity of molecules then measures the amount of electromagnetic energy created when the molecules move back. (yes, that's an oversimplification) Tape recorders use electromagnets to move iron oxide molecules on a tape, forcing a specific magnetic orientation of the molecules that can be read when the tape passes a tape read head. Electromagnets are used to move armatures of electric motors, and the armatures are connected to shafts that rotate, propelling a cruise ship or a locomotive. Electromagnets "move" the electron beam of a CRT, allowing the picture to be displayed on older televisions. That is just an example of a few uses of electromagnets. Keep looking, they are all around us.
How are electromagnets different from magnets?
You can turn electromagnets on and off.
How are electromagnets different from permanent magnet?
You can turn electromagnets on and off.
Where use electromagnets?
Inside of electric motors are electromagnets and permanent magnets. In a metal junk yard large electromagnets are used to pick up metal. In MRI's large electromagnets are used for imaging.
Where are electromagnets used in the home?
Electromagnets are used in many things such as in televisions, blenders, doorbells, and speakers
Could you Find diagrams of electromagnets in televisions?
No.
How are electromagnet usful?
Electromagnets are used in many ways. Televisions use electromagnets to direct the electron beam, whereas loudspeakers and earphones use electromagnets to push the diaphragm forwards.
Why do you need electromagnets?
pick things upAnother AnswerElectromagnets are necessary for an electric motor to work. Electromagnets are used in ink jet printers to release ink, they activate relays and solenoids. Electromagnets are inside automotive fuel injectors. The old CRT televisions wouldn't work without some high powered electromagnets. Computers would be useless without electromagnets that operate disk drives and relays. Electromagnets are an essential part of all transformers.Essentially, modern technology would come to an end without electromagnets.
What things use electromagnets?
Well actually quite a few things use electromagnets such as a tv,remote control car, a phone (I don't know properly :s )and more

What is electromagnets used in?
Electromagnetism is used in electric motors, computer hard drives (and other magnetic storage media), junkyard electromagnets, televisions, particle accelerators, MRIs, and many other devices.
Do televisions have magnets in them?
Yes, at least in the speakers. Some older televisions used them to help direct the electron beam, though mostly electromagnets were used for that.
Where are electromagnets used?
fire bells tv's junk yards and a lot more

How does a TV take advantage of magnetic forces?
A television system takes advantage of magnetic forces by using electromagnets. These magnets control the electron beams, causing them to scan top to bottom and left to right.
How do electromagnetic devices impact on society?
Electromagnets are widely used in the society. An advantage is that humans use electromagnets in all kinds of useful utensils like doorbells, telephones, cranes, computer disks, mobile phones, televisions and so on. Also eye surgeons, while performing operations, use electromagnetic devices to recover the patient.
