On the whole world's major environmental problem is water pollution, due to pollutant water increases in microscopic harmful living organism's counts and it causes change in water odour, taste and colour, which causes the spread of dangerous epidermal diseases. A physical treatment using magnetic field it is beneficial for the control and removing of the scale formation on the walls and heating equipment's but the efficiency of this treatment is still a controversial question. In the present study, like physical parameters total dissolved salts (TDS), electrical conductivity (EC) and pH of sodium chloride solution have been evaluated under the effect of different strength of magnetic field (0.05T-0.15T) for different exposure time (3 hours, 5hours and 7 hours). The electrical conductivity and total dissolved salts rapidly increasing with the exposure of time and pH is increase with time as compared to control but for 3 hours is more and for 7 hour is less. Data collected during the experiment was analyzed statistically (SPSS-20.0). This analysis shows that the increase in TDS, EC and pH under the effect of magnetic field was significant (p < 0.05). The regression analysis was used to show linear relation between TDS and EC of water.
