当电脑显示器的显像管被磁化后，虽然有些显示器可以通过自带的消磁功能来消磁，但消磁能力并不很强或需要较长的处理时间。笔者在工作中常利用电流通过带有磁芯的电阻所产生的磁场来进行消磁，可以达到快速对显示器消磁的目的。 首先将胶质导线或塑料绝缘导线绕成多圈串联在电 When the picture tube of a computer display is magnetized, although some displays can demagnetize through their own degaussing function, the degaussing capability is not very strong or needs long processing time. The author often use current through the magnetic field generated by the resistance with a magnetic core to demagnetize, you can achieve the purpose of rapid demagnetization of the display. First, the plastic wire or plastic insulated wire wound in series in the electricity circle
