| Abstract: | This paper first describes the combination of Hall effect and lock-in amplifier technology, on the basis of which , a high precision magnetic field measurement instrument has been developed to do the measurement and analysis for the cathode ray tube (CRT) deflection yoke magnetic field ,especially for the magnetic field by the correction permanent magnets. The instrument is very useful for the optimum design of CRT deflection yoke without correction permanent magnetic parts. |
