The Magnetic Field

The impacts of strengthening magnetic field exposure on combustion performance of low-octane fuel have been examined experimentally. The combustion test was carried out using a 2-stroke 49 cc engine where the fuel was magnetized using a low magnetic field (<2 kG). Moreover, the molecular behavior of magnetized fuel was also characterized through spectrum tests using NIR and UV-Vis spectrophotometers. The result of this study indicates an exponential decrease of magnetized fuel consumption against the strengthening of magnetic field exposure. This exponential decrease of consumption can be related to the Arrhenius principle. In addition, the decrease of oxygen in the exhaust gas along with the strengthening of the magnetic field also confirms the increase of combustion reactions. Meanwhile, the increase of magnetized fuel absorption against ultraviolet and near-infrared lights along with the increase of the magnetic field intensity indicates a bond weakening, accompanied by the increase of molecular vibrational energy.

The present study was conducted to investigate the effects of electromagnetic field on germination characteristics of pigweed (Amaranthus retroflexus). It was conducted in factorial randomized complete design with three replications in Tarbiat modares University, during 2013-14. Pigweed seeds were subjected to three magnetic field levels created by magnets with 4000G, 5000G and 6000G for exposure times of 5, 35 and 65 minutes followed by which the seeds were placed in petri dishes and transferred on germinator. The germination characteristics, germination percentage, time to 50% germination, germination evenness and the rate of germination were recorded .The sprouts were bisected in four-leaf stage and they were evaluated in their morphologic characteristics and the amount of protein and â-amylase enzymatic activity. Results indicated that the mutual effect of the magnetic field exposure duration and intensity was found significant on all the examined traits in pigweed. The highest and lowest germination in pigweed seeds were recorded with 5000G-5minutes and 6000G-65minutes treatments, respectively. The treatments in which the weed seeds were exposed to 5000G intensity for 65minutes, 6000G for 35minutes produced the highest and the lowest amounts of protein, respectively. Based on the experiment results the magnetic field exposure intensity and duration influence the germination characteristics, protein content and â-amylase enzymatic activity rate, this can be a promised method in controlling the weeds in farms.

The Magnetic Field

We study the effect of promoting low magnetic field exposure on antimicrobial activity against Erwinia amylovora (E. Amylovora) bacterium. For this purpose, we treated E. amylovora at 28°C with two intensities (0.2T and 0.5T) of the magnetic field for one hour to see the intensity of bacterial growth inhibition. Bacterial growth was measured in experimental samples. The results indicate that exposure to E. amylovora to 0.2T and 0.5T for 1 hour reduced bacterial growth. Dielectric relaxation studies of treated and untreated alive bacterium showed changes of the surface charge distribution of the bacterium which indicates changes in the receptor properties and hence cell communications. The study showed bacteria treated with the magnetic field which was exposed for an hour, adjusted its cellular activity, slowing the rate of growth and affecting microbial pathogenicity. The effect was higher at 0.5 T than 0.2 T. We concluded that magnetic field formation is a promising technique for treating this type of bacteria.

The Magnetic Field

In this paper magnetic field of electrical radiant heating system (ERHS) is considered. Typically, cable system of ERHS is planar, and it can be built into the floor, wall or ceiling. The magnetic field generated by ERHS depends on the intensity of the current, which in turn depends on the size of the heating area. According to our results, single wire ERHS can generate magnetic field considerably higher than the background field. Key words: Electrical radiant heating system, magnetic field, magnetic field exposure.
