One of the main challenges in developing magnetic resonance imaging (MRI) systems is to create a static coil that needs to generate magnetic field density along with the characteristics of optimal homogeneity and magnitude size. To do this, two N42 Block PMs are used and the iron core is designed and optimized in accordance with the dimensions of PM pieces using ANSYS Maxwell software. Then, al...

In 1914, Blondel [1] performed an experiment in which a solenoidal coil was coaxial with a region of static magnetic field, such that the magnetic field on the conductor of the coil was negligible. The conductor of the coil T (D in the right figure) could be wound onto an auxiliary drum T ′ (D1), such that the magnetic flux through the coil T (D) was time dependent. What was the reading of the ...

Consider a coil above a conducting plate. The interaction between the probe-coil and the plate is modeled by a quasi-static approximation of Maxwell’s equations: the eddy current model. The associated electromagnetic transmission boundary-value problem can be solved by the integral equations method. However, the discretization of integral operators gives dense, complex and ill-conditioned linea...

The power system network is becoming more complex nowadays so maintaining the stability of the power system is very difficult. So we have designed a 12-pulse based Static Synchronous Series Compensator (SSSC) which is operated with and without integration of Superconducting Magnetic Energy Storage (SMES) for enhancing the voltage stability and power oscillation damping in multi area system. Con...

Static energy meters installed in households, used for billing purposes of the consumption, have shown errors due to conducted electromagnetic interference coming from appliances household situations. This resulted over- and underestimations bill, even a perceived generation. The currents causing are known be nonlinear pulsed with fast slopes. article shows that clipping amplifier, following Ro...

The time-harmonic electromagnetic field in an electrically conductive right-angled wedge due to an inductive excitation by circular coil in air has been calculated. Using a formulation in Cartesian coordinates, the problem domain is truncated in a dimension whose axis is normal to a wedge face, and an approximate series solution found using elementary functions satisfying Maxwell’s equations in...

Introduction: Solenoids are known to be inherently high SNR coils that also generate highly homogeneous radio frequency magnetic (B1) fields[1]. The traditional solenoidal coil generates B1 field that is parallel to the static magnetic (B0) field. Hence, solenoidal RF coils currently in use for small animal imaging are typically designed for large bore clinical scanners, where the RF coil may b...

Induction-coil magnetometers are among the most common devices for measuring both static and transient magnetic fields in accelerator spectrometer magnets. Recent developments have included an induction-coil array mounted on a sledge, which is translated mid-plane of normal-conducting This device, subsequently denoted as moving fluxmeter, used to derive field homogeneity magnet center, well gra...

Rat brain models effectively simulate a multitude of human neurological disorders. Improvements in coil design have facilitated the wider utilization of rat brain models by enabling the utilization of clinical MR scanners for image acquisition. In this study, a novel coil design, subsequently referred to as the rat brain coil, is described that exploits and combines the strengths of both soleno...
