In this paper the effect of direction of external magnetic field on spectral emission of the plasma induced by laser and copper interaction is investigated. Two different experimental setups have been used for this purpose. Two pulsed Nd:YAG lasers with 30 ns and 15 ns pulse duration and energies 150 mJ and 120 mJ, respectively, were used to produce plasma from Cu target and a spectrometer for detecting spectral radiation of the plasma. Two pairs of permanent magnets were used to produce 0.6 T and 0.4 T steady magnetic field across the plasma. Both experiments show the obvious intensity enhancement of the spectral emission lines of Cu by applying external magnetic field. Also, experiments showed that the direction of magnetic field has no obvious effect on spectral emission of Cu plasma
