Abstract

Summary form only given. An inner magnetic shield (IMS) is set inside a cathode ray tube (CRT) to reduce the disturbance from outside of the CRT, such as geomagnetism. The eddy current induced in the IMS due to the changing current in the deflection coil may affect the flux distribution in the CRT. The eddy current is also induced in the electron gun when coils for velocity modulation (VM) are set near the gun. Although the effect of the eddy current is important, reports about the analysis of this phenomenon are few. In this paper, the effect of the eddy current in the IMS and electron gun on flux distribution in the CRT is analyzed by using the 3-D finite element method.
