In this paper, magnetic field with different strength was combined with Au Nanoparticles (Au NPs) in LIBS technology. The spectral intensity enhancement factor of the characteristic line (Cu I 521.8 nm) under different conditions was analyzed and the enhancement mechanism was analyzed. It is showed that when the magnetic field is applied alone, the magnetic field of 153 m T will reduce the spectral intensity. The 20 m T, 50 m T and 90 m T magnetic fields will enhance the spectral intensity, and the stronger the magnetic field, the stronger the enhancement. The application of a magnetic field (magnetic fields enhanced LIBS,MF-LIBS) or Au NPs (nanoparticles enhanced LIBS, NELIBS) alone can enhance the spectral intensity of the plasma, but for the enhancement effect, single constraint is weaker than the combination of the two methods, and the magnetic field confinement is weaker than that of the NELIBS. Through the combination of NELLBS and MF-LIBS, the trace elements can be detected easily.
