A peculiar phenomenon of a gradual decrease of the electric resistivity in the water triggered with a milli-gauss low-frequency pulsed magnetic field was found. A typical decrease ratio of the electric resistivity ρ is about 10% during 40 min., and 20-30% during 15 hours after applying a pulsed magnetic field of 1 milli gauss (mG) and 3 Hz with 1 % duty ratio through 1 s. While the non-magnetized water (Control) with ρ of 8-10 k Ω· m rather increased its resistivity through several hours and then showed almost constant through another several hours.
A mixed water of an, as-prepared water with ρ of 9.24 kΩ· m and a magnetized water of 4.50 k Ω· m also gradually decreased its resistivity after mixing through several hours and days. A higher stability of ρ against cooling (icing) and then warming temperature variations in the magnetized water.
These phenomena stably appear through cool seasons except hot summer season.
