Summary :

This paper describes the characteristics of the radiated magnetic field caused by breaking arcs between a pair of Ag, AgDdO, AgSnO₂ or Pd contacts in a DC 50V/1.9-5.0A circuit. For Ag contacts, in an interrupting current less than 3.3A, the radiated magnetic field appears strongly during the metallic phase arc where the smaller the interrupting current is, the more the number of frequency spectra of the radiated magnetic field becomes. In an interrupting current more than 3.3A, the radiated magnetic field appears weakly during the metallic-gaseous transition period. For AgSnO₂ and AgCdO contacts, there is a weak radiated magnetic field in the metallic-gaseous transition period and the smaller the interrupting current is, the stronger the maximum intensities of frequency spectra of the radiated magnetic field in the transition period are. For Pd contacts, the maximum intensities of frequency spectra of the radiated magnetic field do not change very much from the beginning to the end of the breaking arc, which do not depend on the interrupting current. From the experimental results, the maximum intensities of frequency spectra of the radiated magnetic fields are found to depend on the contact material. And their distribution depends on the impedance of the circuit containing the contacts that generates the breaking arc.
