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.
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.
What can you use electromagnets for?
the window of the car
4 ways how to use electromagnets?
Electromagnets are primarily used to produce electricity Any large scale facility with lots of instruments will definitely have electromagnets in it. Generators in the powerhouse uses big electromagnets to produce AC voltage which is then transported for the commercial or residential use.
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.
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
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.
Does an iron box use electromagnets?
no there is no use of electromagnets in iron box
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.
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 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.

How do cat scans use electromagnets?
CAT Scan does not use electromagnets, its MRI (Magnetic Resonance Imaging) which uses Electromagnets to produce images of the patient's body.
Do ipods use electromagnets?
no
