The laser-induced plasma obtained from the liquid target and
expanding across a steady magnetic field has been studied using
atomic emission spectroscopy. The line emission from the plasma
was enhanced (>1.5 times) in the presence of a magnetic field,
whereas background emission decreases. Enhancement in line
intensity was found to be mainly a function of plasma beta (β).
An increased rate of three-body recombination in plasma particles
due to the cooling of the plasma during its expansion and an
increase in effective plasma density as a result of its confinement
seems to be the reason behind this enhancement.
