This work aims to provide a physical interpretation of the “Maxwell’s displacement current” and generalize the use of the derivative function of the electrical flux “dΨ/dt” in the magnetic field calculation. The innovative contribution of this study is a mathematical model to describe the origin of magnetic field as a variation of electric flux. By this approach, it follows that only the functi...

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...

Accurate detection of weak periodic signals within noise and possibility of secure messaging have made Duffing oscillator (DO) highly important in the field of communication. Investigation on the properties of DO is thus ardently sought for. An elegant approach to accomplish the same is to fabricate electronic circuit simulating DO non-linear equation and to study the effect of input signal amp...

An approach to increase the capabilities of integrated circuit nonvolatile memory is to take advantage of the hysteresis in the polarization of ferroelectric materials. For a rigorous analysis of the resulting devices, a suitable model for the ferroelectric effects has been developed. We present this model and show the results of its implementation into a device simulator. Although this model w...

In this paper, Intelligent water drop algorithm (IWD) is used to analyze single overhead line connected to grid-grounded arrester. In this approach, at first Norton’s equivalent circuit of the overhead line over lossy soil is computed by method of moments (MoM) and then for the problem under consideration, a nonlinear equivalent circuit in the frequency domain is proposed. Finally applying inte...

A new approach to synthesis of permutation class of quantum logic circuits has been proposed in this paper. This approach produces better results than the previous approaches based on classical reversible logic and can be easier tuned to any particular quantum technology such as nuclear magnetic resonance (NMR). First we synthesize a library of permutation (pseudobinary) gates using a Computer-...
