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 can you demagnetize a small object?
You can demagnetize a small object by exposing it to a strong magnetic field in the opposite direction to its current magnetization. Another method is to subject the object to high temperatures, which can disrupt the alignment of the magnetic domains and demagnetize it.
Can you demagnetize a magnet and if so, how?
Yes, you can demagnetize a magnet by subjecting it to high temperatures, hammering it, or exposing it to a strong magnetic field in the opposite direction.
How to demagnetize a magnet?
To demagnetize a magnet, you can expose it to high temperatures, pass an alternating current through it, or subject it to strong impacts. These methods disrupt the alignment of the magnetic domains within the magnet, causing it to lose its magnetism.
How long does it takto demagnetize an object?
The time it takes to demagnetize an object can vary depending on the size and material of the object. Small objects can be demagnetized in a fraction of a second using an appropriate demagnetizing tool or technique, while larger objects may take longer.
How do you demagnetize a Rolex watch?
To demagnetize a Rolex watch, you can take it to an authorized Rolex service center where they have the necessary tools to perform the demagnetization process. It involves using a demagnetizing machine to remove any magnetic interference that may affect the watch's accuracy. It is not recommended to attempt demagnetizing a Rolex watch yourself unless you have the proper training and tools.
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."
How can you demagnetize a small object?
You can demagnetize a small object by exposing it to a strong magnetic field in the opposite direction to its current magnetization. Another method is to subject the object to high temperatures, which can disrupt the alignment of the magnetic domains and demagnetize it.
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.
Can you demagnetize a magnet and if so, how?
Yes, you can demagnetize a magnet by subjecting it to high temperatures, hammering it, or exposing it to a strong magnetic field in the opposite direction.
What are the ways of demagnetize the magnet?
By keeping them in magnet keepers
What did gilligan put in the robot to demagnetize it?
lucky rabbit's foot
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.
