<p>The process of eliminating magnetization on a <span class="caps">CRT</span> is called degaussing (the unit of measure of magnetic inductive force is the gauss, named for mathematician Karl Friedrich Gauss). Most modern CRTs today include built-in degaussing circuits. Some have a manual switch to activate the circuit, some do it automatically and some offer both as an option. The degaussing circuit uses a coil of wire to neutralize magnetic fields within the <span class="caps">CRT</span>.</p>

<p>Hello,<br /> Can you please help me with a question: a month ago a friend of mine accidentally held a tip of a pretty strong magnetised screwdriver very close to my lg flatron 775ft, a crt monitor, while demonstrating something. There were magnetic distortions on the screen around the tip of the screwdriver. He waved with the screwdriver near the monitor surface for about 20-30 seconds until holding it back. Is it possible that this kind of event left permanent damage to the monitor? In terms of picture clarity and refresh rate? Perhaps it is only my autosuggestion, but it feels as if the image is a bit ‘blurrier’ now and more stessful for my eyes (as if i am looking at a screen with lower refresh rate, like below 70Hz, when it is 85Hz). Thanks for answering</p>
