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
no there is no use of electromagnets in iron box
things like tosters, microvaves, fridge, freezer and so on ..............
Electromagnets are used in many things such as in televisions, blenders, doorbells, and speakers
CAT Scan does not use electromagnets, its MRI (Magnetic Resonance Imaging) which uses Electromagnets to produce images of the patient's body.
no
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.
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.
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.
yes
the window of the car
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.
The ancient Greeks understood magnets but since they did not have a source of electricity, they did not use electromagnets. They did make compasses.
