A finite element model to simulate magnetic field distribution and laboratory studies in wet low-intensity magnetic separator

Beneficiation of a low-grade iron ore by combination of wet low-intensity magnetic separation and reverse flotation methods

Beneficiation of a low-grade iron ore was investigated by combination of the low-intensity magnetic separation and reverse flotation methods. The main constituents of the representative sample were 36.86% Fe, 8.1% FeO, 14.2% CaO, 13.6% SiO2, and 0.12% S based on the X-ray fluorescence, titration, and Leco analysis methods. The mineralogical studies by the X-ray diffraction, scanning electron mi...

Finite Element Analysis of Stationary Magnetic Field

Three-dimensional calculations of the magnetic fields in a finite superconducting hollow cylinder in an applied axial magnetic field

In this study, a set of self-consistent coupled-integral equations for the local magnetic flux and current distributions in a finite superconducting hollow cylinder under an axial magnetic field has been directly derived by using the Biot-Savart law within the framework of the critical-state model. The equations were first solved numerically in the three-dimensional space before obtaining the h...

Study on Fe3O4 Magnetic Nanoparticles ‎Size Effect on Temperature Distribution ‎of Tumor in Hyperthermia: A Finite ‎Element Method ‎

   In recent years, Hyperthermia has been used as an emerging technique for cancer treatment, especially for localized tumors. One of the promising cancer treatment approaches is magnetic nanoparticle (MNPs) Hyperthermia. In this theoretical work, the temperature distribution of a common tumor over the different sizes of Fe3O4 magnetic nanoparticles, namely 25, 50, 100, and 200 nm, was stud...

a study of biological effects of magnetic field and the evaluation of magnetic field intensity in an aluminium reduction plant

the exposure of workers to magnetic field that occur in aluminum reduction potrooms has been studied. the pattern of magnetic field intensity has been demonstrated along the shop. it has clearly been shown that the personnel working near the pots are exposed to 20-to 1000-gauss magnetic field. to set limits of exposure to magnetic fields, the literature on the biological effects of stationary m...

Effect of a static magnetic field on bone healing in the dog: radiographic and histopathological studies

Although the promotional effects on bone healing of pulsed electromagnetic fields (PEMF) have beenwell demonstrated, the effects of static magnetic fields (SMF) remained unclear. In this study, effects of acustom-made magnetic wrap on radiographic and histopathological aspects of bone healing using a canineunstable osteotomy gap model were investigated. After an osteotomy of the midshaft radius...
