A "degaussing coil" is used to demagnetize the cathode ray tube (CRT) types of television. LCD and plasma type TVs would NOT need this done. What would happen on CRTs is if they were exposed to some other external magnetic fields, it would cause the electron beam that creates the illumination on the screen to deviate from its intended position, thereby causing color "splotches". The degaussing coil is a round-shaped hoop usually powered by a 120 VAC wall outlet (in the US) creating a fluctuating magnetic field. The technician starts close to the face of the TV and moves the hoop in a circular motion (you'll see the screen make some really rainbow-like colors) and SLOWLY backs it away from the screen. When you no longer see any effect from the degaussing coil, the process is complete. Newer TVs usually had a degaussing coil built into the TV set, which it would energize occasionally to keep the screen degaussed.

How do you demagnetize a old pocket watch?
you rub a piece of sand paper on it
How you can demagnetize materials?
A magnet has magnetic properties because the dipoles of the atoms are lined up in a single direction. To demagnetize it, you must scramble the dipoles out of alignment. First, heat the magnet past the Curie point (the temperature at which it loses its magnetic properties until cooled). Strike it on the ends of the magnet with a hammer. When cooled, it will no longer be magnetized.
How can you use a solenoid to make a temporal magnet?
Passing it through a coil that has a DC current through it. The DC current creates a field which allows the realignment of electrons in the solenoid, allowing it to have temporary magnetic properties. Passing an AC current through the coil would demagnetize the solenoid.
How do you demagnetize a magnetized iron nail?
Rapidly rub the iron with the steel magnet for approximately 2 minutes for every pound of iron. Repeat on all sides of the piece of iron. Repeat process as needed until demagnetized.
What is the difference between plasma the state of matter and plasma tv?
There is no difference the only thing is plasma is in a TV in plasma screen TV and plasma is outside of the TV in the state or matter.
How do you use demagnetize in a sentence?
"It is best to demagnetize metal objects before using them around magnetic tape drives." "Heat tends to demagnetize ferrous minerals."
Can you demagnetize a magnet with a magnet?
no you can't
How is electromagnetism useful?
electromagnets are used to produce an electric current. they are often used to hold objects, demagnetize them such as audio tapes and TV screens.
What are the ways of demagnetize the magnet?
By keeping them in magnet keepers
How can you demagnetize gold?
Bring it to me. I will do my "special technique" to demagnetize it. You know, sell it and not give you any of the money. Gold isn't magnetic, so if you got some that IS it's got iron in it.
What does demagnetize mean?
It means to make something not magnetic anymore
What did gilligan put in the robot to demagnetize it?
lucky rabbit's foot
Will exposing a magnet to a DC magnetic field demagnetize it?
Obviously no.
Why does your TV have rainbow shadows around everything?
Unfortunately, if you're seeing that, it's too late. What that means is that your TV is too close to a magnetic source, such as a speaker. If you catch it in time, it will eventually demagnetize and the picture will return to normal, but if it's around everything, I'm pretty sure it's too late. Long answer short, the reason your TV has rainbow shadows around it is because it's time for a new one.
Is it impossible to demagnetize steel using iron?
No. Steel is mostly iron.
How do you demagnetize a old pocket watch?
