23 With the development of superconducting magnets, the chances of exposure to 24 intense static magnetic fields (SMFs) have increased. Therefore, safety concerns related 25 to magnetic field exposure need to be studied, especially the effects of magnetic field 26 exposure on the central nervous system. Only a limited number of studies prove a direct 27 connection between magnetic fields and el...
There is the magnetic coupling among control windings of controllable reactor of transformer type (CRT), the decoupling integrated magnetic technology is applied to the structure design of CRT in this paper. To realize the decoupling among the control windings we propose a magnetic integrated structure of CRT by providing low magnetic resistance magnetic circuit for control windings magnetic fl...
In Figure 2, the shape is the same as Fig. I, but the axis labels and values have been changed. Figure 2 shows the characteristic of a specific core made from the material of Figure I. The flux density axis Magnetic Fundamentals: Units commonly used in magnetics design are given in Table I, along with conversion factors from the older CGS system to the SI system (sysfeme infernationalrationaliz...
We have developed the 2.0T permanent magnetic circuit for NMR/MRI (figure1). In the previous study, the maximum field strength of permanent magnets for MRI was 1.0T [1, 3]. With using NdFeB magnetic materials and a special magnetic circuit design, it has been achieved that the magnetic field strength of 2.03 Tesla, H center frequency of 86.3MHz, air gap of 60 mm, 10 ppm-homogeneous volume of 30...
Volume integral formulations for solving electromagnetic problems in the frequency domain are proposed. Firstly, it is based on a magnetic flux B and current density J facet interpolation for representing the electromagnetic problem through an equivalent circuit. Secondly, magnetic vector potentials A and electric vector potential T are considered thanks to discrete geometric approach. The form...
