The current study involves the effect of zeta potential and magnetic field on the physical properties (electrical conductivity, total dissolved solid, contact angel and surface tension) so as the absorbance by (UV-Visible) on the water in order to compared with them. Also, the use three magnetic devices with different intensities (1000, 2500, 5000) Gauss and zeta rod (ZRS-R) with constant voltage (30±) Kv. The operation system in zeta rod depended on re-cycling the water and sampling during (30, 60, 90) min, but in magnetic treatments were used the water directly after magnetized it. The physical tests showed a clear improvement in the properties of water especially in the surface tension and contact angel about 10% of the original value to the zeta rod treatment and 15% for magnetic treatment in the intensity 5000 Gauss also the results showed the increasing in absorbance, TDS, CON comparing with untreated water. The obvious improvement of the water physical properties approve that magnetic treatment is more effective about7% than zeta rod, especially in the high intensities.
