In this paper, the technology for fabricating NiFe/Cu/NiFe layered structures by magnetron sputtering is presented. Two series of samples were fabricated on a glass substrate with a layered structure, where the individual layers were 30 nm NiFe, 5 nm Cu, and finally NiFe with a thickness of 30 nm. The series differed in the type of technology mask used. A constant magnetic field was applied to the substrate during the sputtering of the ferromagnetic layers. Measurements of the DC resistance of the obtained structures in the constant magnetic field of neodymium magnet packs with a constant magnetic field of about 0.5 T magnetic induction have been carried out. Comparison of the two series allows us to conclude the greater validity of using masks in the form of Kapton tape. The obtained results seem to confirm the occurrence of phenomena referred to as the giant magnetoresistance effect.

The authors discuss the effects of static magnetic field (SMF) exposure based on reviewed literature reports. The systematic review covered both research carried out directly with people as well as studies with animals. A review was carried out in terms of various potential effects: carcinogenic effects, reproductive and metabolic disorders or the influence of SMF on the nervous and circulatory system. The possible biophysical and biological effects of the SMF were also described. Med Pr. 2019;70(1):107–20

The paper presents the technology for obtaining NiFe/Ti/NiFe layer structures in MEMS technology using magnetron purge with the assumption of being used as semi-magnetic sensors. A series of samples was made on a glass substrate with a sandwich structure, where the individual layers were 100 nm NiFe, 10 nm Ti and on top again NiFe with a thickness of 100 nm. Measurements of DC resistance of the obtained structures in a constant magnetic field, which was produced by neodymium magnets and an electromagnet, were carried out. The obtained results confirm the occurrence of phenomena known as the magnetoresistance effect. The influence of the spatial arrangement of structures relative to the constant magnetic field vector was checked and proved.

Aeration is the main item in the operating costs of most wastewater treatment plants. New, efficient methods of aeration are constantly requested. Even a small increase in the efficiency on the larger scale of the process provides significant financial savings. The paper presents the possibility of increasing the efficiency of oxygen transfer through the use of a static magnetic field. The aim of the study was to evaluate impact of static magnetic field on efficiency of fine-bubble aeration of liquid. The experiment were conducted in constant temperature (24°C) at pH 8.25. The aeration intensity was 58 L/h. The mean magnetic field induction ranged from 10 mT in a series 1, to 14 mT in a series 2 and 16 mT in a series 3. The OC value in case of the use of the lowest induction was 75.22 g/(m3•h). In series 2 the OC value was an average of 77.7 g/(m3•h). In series 3, when magnetic field with the highest induction was used, the OC value was 92.72 g/(m3•h). While in the control series, without the use of static magnetic field, the OC was only 60.5 g/(m3•h). Positive experiments results in laboratory scale tent to research on possibility for application of static magnetic field to enhance the efficiency of aeration in industrial devices.

Introduction: Magnetic field is used in therapies designed for patients with rheumatic disorders such as rheumatoid arthritis (RA). The question of selecting adequate treatment parameters to obtain optimal therapeutic effects still needs to be answered. The purpose of the study was to assess the influence of magnetic field, depending on its nature, on problems and dysfunctions experienced in upper limbs by patients with RA.

The effect of magnetic radiation on the prooxidant-antioxidant system and alkaloids level in Jimson weed (Datura stramonium L.) have never been studied and reported before. The objective of this research was to study the influence of static magnetic field on the homeostasis and alkaloids level in D. stramonium. The level of (thio) barbituric acids active products, superoxide dismutase and catalase activity in D. stramonium seedlings under the influence of static magnetic field with the intensity of 3 mT and 10 mT at two exposure times, 30 min and 22 hours, was studied. Under these conditions, the level of alkaloids in the extract from leaves and stems of germs was determined by chromatographic analysis. An increased level of lipid peroxidation products, the activity of superoxide dismutase and catalase in seedlings under the long-term effect of magnetic field were observed. The level of scopolamine alkaloid depended on the duration of exposure to the static magnetic field; however, this factor did not effect the atropine level. The obtained experimental data was confirmed by the results of the analysis of variance.
