The purpose of the research was to establish the mechanism of the magnetic field impact on seeds to determine the most effective mode of pre-sowing treatment of seeds in a magnetic field and design parameters of the device for magnetic treatment of seeds. It is established that under the influence of a magnetic field the rate of chemical reactions occurring in plant cells is accelerated, solubility of salts and acids increases, and permeability of cell membranes accelerates the diffusion of molecules and ions through them. This leads to an increase in the concentration of ions in the cell and oxygen molecules and the growth of water absorption of seeds. Pre-sowing seed treatment promotes increased germination by 25-40%, and germination by 30 - 35%. The most effective pre-sowing treatment of seeds in a magnetic field is a magnetic induction of 0.065 Tl with four reversal magnetization, a pole division of 0.23 m and a seed movement speed of 0.4 m/s. With this mode of treatment, crop yields increase by 20–25%.

The Magnetic Field

It is possible to increase crop yields and product quality through the use of electrophysical methods of pre-sowing seed treatment, among which pre-sowing seed treatment in a magnetic field is promising. For successful introduction of magnetic seed treatment in production it is necessary to establish mode parameters of treatment and their optimum values. To do this, it is necessary to establish the effect of the magnetic field on the change in activation energy during pre-sowing seed treatment. The aim of the study was to determine the change in activation energy during pre-sowing treatment of crop seeds in a magnetic field. To determine the change in the activation energy, the change in the biopotential of the seed during its treatment in a magnetic field was experimentally investigated by the experimental planning method. It was found that the change in seed biopotential depends on the square of the magnetic induction and the velocity of the seed in a magnetic field. An analytical expression was obtained that relates the change in activation energy to the change in seed biopotential, which made it possible to establish the dependence of the change in activation energy on the treatment parameters. It was found that the greatest seed biopotential and activation energy change at a magnetic induction of 0.065 T, a magnetic field gradient of 0.57 T/m and a velocity of 0.4 m/s. Under this mode of pre-sowing seed treatment of agricultural crops, the activation energy changes by 3.1 - 5.7 kJ/g-eq.

Pre-sowing treatment of seeds in a magnetic field can increase crop yields, reduce the incidence of plants and improve product quality.Research purposeTo analyze the mechanism of the magnetic field influence on seeds, determine the most effective mode of pre-sowing treatment of leguminous crop seeds in a magnetic field and design parameters of the equipment.Materials and methodsThe authors have determined that under the influence of a magnetic field, the rate of chemical and biochemical reactions in plant cells increases, the transport of ions and molecules through the cell membrane increases, and the membrane permeability increases, so the sowing qualities of seeds improve and their yield increases. Experimental studies were carried out with seeds of "Adagumsky" peas variety and "Gribovsky" beans variety, using the experiment planning method. Magnetic induction and the velocity of seed movement in a magnetic field were taken as influencing factors.Results and discussionWith a change in the magnetic induction from 0 to 0.065 T, the germination energy, germination, biometric indicators, and the yield of peas and beans increase, while with further increase in magnetic induction they decrease. It has been revealed that the use of four-time magnetization reversal enhances the effect of magnetic seed treatment. The velocity of seeds is a less significant factor than magnetic induction. The most effective treatment mode occurred at an energy dose of 1.90 J·s/kg for peas and 1.86 J·s/kg for beans, which is provided for a pole division of 0.23 metre. The authors have designed a plant for pre-sowing treatment of seeds in a magnetic field, which consists of four pairs of magnets installed in parallel above and below the conveyor belt with variable polarity.ConclusionThe most effective pre-sowing treatment of leguminous crop seeds in a magnetic field is a magnetic induction of 0.065 T with fourfold reversal and a conveyer movement speed of 0.4 metre per seconds, which provides an increase in peas yield by 42 percent, and that of beans – by 23 percent.

Permanent magnets of different intensities were used to investigate the effect of a magnetic field in the process of preventing deposits of calcium carbonate. The magnets were fixed on the water line from the tap outside. Then heating a sample of this water in flasks and measuring the amount of sediment in a manner weighted differences. These experiments comprise to the change of the velocity of water flow, which amounted to (0.5, 0.75, 1) m/sec through the magnetic fields that are of magnetic strength (2200, 6000, 9250, 11000) Gauss, and conduct measurements, tests and compare them with those obtained from the use of ordinary water.The results showed the effectiveness of magnetic treatment in reducing the rate of deposition of calcium carbonate where up to 60% after treatment, and this percentage is increasing with increasing magnetic field strength where up to 85% when the intensity of the magnetic field 9250 and 11000 Gauss at the velocity of the water flow of 0.75 m/sec. This percentage of reducing was investigated with increasing the velocity of flow of water through a magnetic field.

The Mg–0.6Al–20.8Gd (wt.%) alloys were homogenized at 620 °C for 20 min under 0 T and 1 T, followed by furnace cooling, quenching, and air cooling, respectively. The effects of the magnetic field on the phase constituent, microstructure, secondary phase precipitation, and mechanical properties of the Mg–Al–Gd alloys were investigated. The Mg–Al–Gd alloys contained α-Mg, Mg5Gd, Al2Gd, and GdH2 phases, and the phase constituents were hardly influenced by the applied magnetic field. However, the precipitation of the paramagnetic Mg5Gd upon cooling was accelerated by the magnetic field, and that of the ferromagnetic Al2Gd phases was inhibited. In addition, the Al2Gd phase was significantly refined and driven to segregate at the grain boundaries by the magnetic field, and the resultant pinning effect led to the microstructure change from dendritic α-Mg grains to rosette-like ones. When the magnetic field was only applied to the homogenization stage, the content of the Mg5Gd phase remained unchanged in the quenched alloy, whereas the Mg5Gd laths were significantly refined. By contrast, the contents of the Al2Gd and GdH2 phases were increased, while the precipitation sites were still within the α-Mg grains. The Mg5Gd laths were incapable of providing precipitation strengthening, while the Al2Gd and GdH2 particles brought positive effects on the enhancement of the mechanical properties. In the quenching condition, the hardness, compression strength, and ductility can be improved by the magnetic treatment, whereas these mechanical properties can be suppressed in the furnace cooled condition by the magnetic treatment.

This paper presents finite-element analysis (FEA) of the magnetic field of a magnetic gear mechanism. An external type magnetic gear mechanism, which consists of two identical magnetic gears with sector-shaped permanent magnets, is introduced first. Then, the magnetostatic field distribution and transmitted torque of the magnetic gear mechanism are simulated by a commercial FEA package Ansoft/ Maxwell. Next, the effects of design parameters, including the air-gap length, the number of magnetic pole pairs, and the height of permanent magnets, on the maximum transmitted torque are discussed. The results of this work are beneficial to the design of magnetic gear mechanisms.

The article considers the possibility of increasing the efficiency of chemical reagents by treating inhibited solutions with a magnetic field. It is shown that a various method for generating the magnetic field has a different effect (Some positive some negative). The best results can be achieved with anti-scale magnetic treatment using permanent magnets. Modified inhibitors (after magnetic treatment) have enhanced protective effectby their adsorption capacity with respect to metal increases.
