Abstract
A degaussing circuit for compulsorily degaussing a picture tube of a CRT monitor by causing alternating current to flow through a degaussing coil. A switching part, connected to a first end of the degaussing coil, switches a current flowing into the degaussing coil on/off. A chargeable device connected to the first end or to a second end of the degaussing coil removes a potential difference across the degaussing coil when the switching part is turned off. Alternatively, chargeable devices may be connected to both the first and second ends of the degaussing coil. Thus, an electromagnetic field is prevented from being generated by the residual current in the degaussing coil, to thereby meet electromagnetic field safety standards for the monitor.
