Indeed, the present paper focuses on the search of the most decisive parameters, which influence the process of magnetization of water using a special magnetic device, which generates a low electromagnetic field of 40 nT. The outcomes of this work will be very helpful for engineers in agriculture and in other industrial fields.

.1 Materials description
The aqua-4D Magnetic water treatment is a physical process based on quantum mechanics and electromagnetism [28]. To detect the action of the electromagnetic flux density on water, a specific equipment was realized in the laboratory. It consists of an apparatus that generates the electromagnetic field, a pump, sensors connected to a computer to follow the magnetization of the water ( Figure 1). The experiment consists of pumping the water from one tank to the other by passing it through the electromagnetic apparatus. The figure 2shows the method of heating the magnetized water and tap water to do a comparative study by visualizing the electromagnetic field at equilibrium, during heating and cooling of both types of water. The monitoring of the electromagnetic field was done by the Kobra software. The data were automatically recorded.

The rearrangement of moleculesH 2 O
The figure 3 depicts the main elements of water, which are hydrogen bond ( Figure 3a) and dipole moment (Figure 3b), ensuring cohesion between water clusters without electromagnetic field and in the existence of the magnetic field flux. They respond to the influence of the energies coming from outside. 3 Results and discussion 3.1 magnetization phenomenon of water In order to check the capacity of storing water for the electromagnetic energy, we have investigated the evolution of the magnetic field received, during treatment by the electromagnetic field, generated by the Aqua-4D device (Figure4).
The linear regression of the fluctuations of the magnetic field received by the tap water shows a decrease in a non-zero value (0.0075 mT) after eight hours (28800 s), which shows the magnetization phenomenon of water. Consequently, the water is a substance having the ability to store electromagnetic energy. During the 15h of electromagnetic treatment, the recorded magnetic field fluctuations, are relatively low (Bmax=0.0230mT and Bmin=-0.025mT) with an average value of 0.0015mT. This variation is slightly greater than the value measured before the application of the electromagnetic field. These assessments of the flux density of the magnetic field allowed us to monitor possible fluctuations in this field after the exposure of both types of water (magnetized water (MW) and tap water (TW)) to the electromagnetic field. The experiments indicate that tap water has indeed become magnetized after the treatment by the flux density of the magnetic field generated by the aqua-4D device. The evolution of the static magnetic field after the electromagnetic treatment generated by the aqua-4D device was followed. The experimental results show that during the 15h of electromagnetic treatment, the recorded magnetic field fluctuations are relatively low (Bmax=0. 023mT and Bmin=0. 008mT) worth an average of 0.0155mT for magnetic water, whereas for tap water the obtained values are Bmax=0. 0185mT and Bmin= 0.005mT with a Bavgof 0.01175mT. The measurements of magnetic field allow to monitor the possible fluctuations of this field after the exposure of the samples to the electromagnetic field.

Effect of temperature on EMF intensity and magnetization time
According to literature [29], the thermal agitation of water causes a rotational motion of hydrogens (positively charged) around the oxygen nucleus (negatively charged), which forms an electric current with a short duration generating a Lorentz force in a uniform static magnetic field which influence on chemical and physical properties of water. Indeed, for a better concrete of the effecting of temperature on the magnetization water phenomenon, we have proceeded to a variation of the temperature and observe the influence of this variation on the time of magnetization of water.
The figures 5 illustrate the influence of temperature on the effect of magnetization by the electromagnetic field generated by the Aqua 4D apparatus. According to the previous figure, the water passes through an electromagnetic field, becomes magnetized water (MW). The time of magnetization at 26.5 °C, 40°C are 15 h, 12h respectively, so there is a difference of 3h as TM between the two conditions of temperature. Consequently, the increase of temperature decrease the time of magnetization of water. Concerning the relation between the intensity of magnetic field and temperature we have observed that the Bavg at 26.5°C is equal to 0.020 mT, but at 40°C the value of Bavg does not exceed a value of 0.002 mT. So, the increase of temperature decreases dramatically the intensity of magnetic field. This experimental observation is in conformity with the fundamental laws of electromagnetisms magnetic moments. The thermal agitation of water molecules causes a disorder by Brownian motion and the disappearance of the magnetic order.

Effect of Salinity on EMF intensity and magnetization time
The water is diamagnetic, in the presence of a magnet; the water's diamagnetism will repel the magnet. When salt is added, it increases the intensity of the water's magnetic field. So, we have tried to study this phenomenon. Indeed, we proceed to a variation of the salinity at a fixed temperature of 26.5 °C leaving the conductivity of the water increases during the action of electromagnetic field. The profile of variation of the electromagnetic field as a function of time in the case of salty water in comparison with that of tap water indicates that the electromagnetic field is affected by the salinity. The impact of salinity on the intensity of EMF is very weak (Figure 6), indeed the intensity of EMF at salinity (0.048g/l) is B avg = 0.020 mT, the increase of salinity by 35.952 g/l caused a slight increase of intensity of magnetic field (IMF) by 0.0025 mT so, the impact of salinity on IMF is very weak. Concerning the time of magnetization (TM) of water, we observe the decrease of TM with salinity, therefore at salinity of 0.048 g/l, the time of magnetization is equal to 11.5 h, but at salinity of 36 g/l we obtained 15 h as TM, so the increase of salinity extended the TM ( Figure 6). Thus, the factor of salinity promotes the magnetization of water by extending the time of magnetization of water with a weak impact on intensity of magnetic field.

3.4Effect of pH on EMF intensity and magnetization time
In literature [30], some works have studied the effect of magnetic field on water characteristics, specially the variation in the pH on treated and no treated water. In our case we have focused on the effect of pH on EMF intensity and magnetization time. The results are depicted at figure 7. According to figure 7, the intensity of magnetic field at pH=2 (very acidic environment) the intensity of magnetic field is equal to 0.018 mT. The increase of pH from acidic to basic pH=8.25, increases the intensity of magnetic field by 0.002 mT, so the impact of variation of pH on IMF is weak. in other side, concerning the impact of pH on the time of magnetization of water we observe the following. The time of magnetization at pH=2.00 is15 h, but at pH=8.25 we obtained a value of 15.30 h as time of magnetization, so the influence of the pH at time of magnetization is very slight.

Effect of water velocity on EMF and magnetization time
Among the most parameters cited in the studies of water magnetization, we found the velocity parameter. For example, F. Alimi et al. [31] have tested the variation of the efficiency of the magnetic treatment when the flow velocity was changed. In our case we have studied the effect of water velocity on EMF and magnetization time. The results are depicted in figure8.

Conclusion
According to the results of the present work, we can conclude the following: The water owns the ability to store the electromagnetic energy. The important factors which increase the performance of electromagnetic devices are the salinity, the speed of water and temperature. The increase of salinity causes a variation of the intensity of magnetic field and extends the magnetization time by 3 hours. The thermal agitation of water declines the intensity of the magnetic field and extends the magnetization time by 3 hours. The variation of pH has a slight effect on the intensity of magnetic field but not on the magnetism time. The variation in the water velocity affects the magnetic field of water and the time of magnetization. The variation of water velocity by 0.13 m/s caused an increase of 0.004 mT and extended the time of magnetization by 2 hours.
