How to recover a magnetized display

For ordinary users, the display is very annoying to be magnetized, especially for those who do not have degaussing function of the display itself is even more troublesome. In fact, the solution is not difficult, for strong electromagnetic interference magnetization of the display, it is best to use special degaussing equipment to complete, such as degaussing rods and degaussing coils.

Degaussing stick is a kind of short stick equipment which is produced for the problem of the display magnetization, which is sold in the general electronic market. When used, hold it in front of the monitor screen, take the center of the screen as the centre, do the circular motion of the radius gradually enlarge until degaussing is finished. If the effect of one time is not obvious can do more than a few times. The advantage of the degaussing stick is that it is easy to buy and use, and the average consumer can operate correctly.

Degaussing Coil is the application of magnetic induction principle: through the coil of alternating current in the geometric center of the loop to produce an alternating magnetic field, using the alternating magnetic field of the display in the geometric center of the cathode degaussing, so as to achieve the purpose of degaussing. Use degaussing coil for degaussing, hand-held coil, the screen from a certain edge began slowly to the center of the circular movement, reached the center of the screen and then turn to the outer ring rotation, so repeatedly. The end operation is to place the coil in the center of the screen and make it 90 degrees from the surface of the screen, keep the vertical slowly back to the monitor 1m, then turn off the power, reboot, and carefully observe the degaussing effect. If the effect is not good, can be repeated, until completely eliminate the display due to magnetization caused by abnormal phenomenon.

The advantage of degaussing coil is the obvious disadvantage is that the operation process without degaussing stick is simple. Degaussing Coil also has a major advantage is the production of simple, general computer players can do a hands-on, as long as the attention to good details, the effect of the degaussing coil is still very good. The production of their own degaussing coil, not only can save maintenance expenses, and through hands-on operation, but also to enable operators to obtain DIY fun and sense of achievement, why not?

First of all, need to prepare some materials: a few meters of enameled wire, a circular plastic frame, insulating electric tape, insulation rods (one meter) and so on.

The method of making: the enameled wire (colloid conductor or plastic insulated wire) parallel around the circular plastic box, at the same time pay attention to the winding turns can not be too little, otherwise the resulting magnetic field is too small, no actual effect, turn the number can not be too much, otherwise the resulting magnetic field is too strong, against the surrounding electrical equipment and disadvantage. In the actual operation as long as the completion of the preparation of a few meters of enameled wire can be, not too much or too little. After winding, will be insulated electric tape around paste in the round plastic box, can paste two to three layers (at least two layers, and must be round plastic frame and enameled surface all paste good), so that plastic frame and enameled wire fixed together. Next, place the end of the insulating stick on one side of the fixed circular plastic frame and paste it with an insulated tape. Finally, the enameled wire is connected in series with a large load of household appliances (such as electric stove, heater or rice cooker) or used to remove the degaussing coil special resistor. The degaussing coil in series in the large load electrical appliances or special resistors, is to reduce the degaussing coil in the use of the current intensity to reduce calorific value. Otherwise, when the degaussing coil is used, its calorific value is very high, easy to burn through the insulating layer of enameled wire, resulting in short circuit.

However, reducing the current in the circuit, will make the magnetic field strength of the degaussing coil drop, degaussing effect will not be obvious, the solution is to increase the number of winding enameled wire. To increase the number of turns of enameled wire at the same time, it should be noted that the above mentioned turns the effect of the size of the magnetic field. Degaussing coil is done, in use, will be large load of electrical equipment into the mains, the degaussing coil in the current will make degaussing coil next to generate magnetic field. The user holds the insulated rod and does not have the end of the degaussing coil connected to the monitor for degaussing. Specific methods of operation have been mentioned above.

The production and use of degaussing coils should also pay attention to the following points:

1, degaussing coil size should be used with the CRT display match;

2, insulation adhesive tape layer of at least two layers to ensure insulation effect;

3. After weighing the calorific value of the degaussing coil and the required magnetic field intensity, determine the number of turns of the degaussing coil (A.T);

4, if conditional, can be in the degaussing coil circuit in Series A thermistor, so degaussing coil at work, according to the operating temperature automatically adjust the current value, to ensure the use of safety. The temperature limit and the resistance of the thermistor shall be determined according to the length of the enameled wire of the degaussing coil and the large load electrical apparatus in the circuit;

5, the use of the process should be avoided damage insulating layer, to ensure the safety of degaussing coils;

6, the use of the process should be used insulation rods, it is best not to contact the degaussing coil with the hand.
