Abstract
This paper deals with the measurement and analysis of the induced voltages and magnetic fields caused by the operation of home appliances. The induced voltage and magnetic field measurement circuit used in this work consists of the induction coil, the operational preamplifier and the active integrator. Television set and monitors for personal computer cause strong magnetic fields rich in harmonics and high induced voltages by using the switching power suppliers. The strong magnetic field intensity and high induced voltage were created by 14" television set, and their values are 2.1 ［$\mu$Tp-p］and 140 ［mVp-p］at the distance of 0.4 ［m］, respectively. However, the induced voltage per unit magnetic field intensity was created by 17" monitor for personal computer and the measured data was approximately 560［mV/$\mu$T］at the same distance. distance.
