Magnetic Fields (inductance and impedance) Every wire used to transmit AC power creates a magnetic field while current flows through it. The magnetic field is visualized by concentric rings around the cross section of the wire each ring closer to the wire has a stronger magnetic power. Magnetic fields are useful for making very strong magnets (when in a coil) i.e. making motors and generators however these magnetic

Permalloys are well known to have superior soft magnetic properties in terms of losses permeability and magnetic field annealing response and lower saturation induction but are more expensive than Si steels so fewer implementations in electric motors have been reported . The permeability peaks only at a narrow range of approximately 75 –80 Ni therefore most commercial
The joint-free superconducting annular disks and their stacks obtained by cutting REBCO (REBa2Cu3O7–δ RE rare earth) wide tapes are proposed as promising passive magnetic shields in this paper. The shielding properties of the disks have been numerically studied using the finite element method. The shielding factor (SF) defined as the ratio between the applied field and the central

The most familiar magnets are permanent magnets like the ones on a refrigerator door. However for applications in transformers and motors soft magnets that can rapidly switch their magnetization in response to a magnetic field are used. In electronics wide bandgap semiconductors such as silicon carbide will allow power conversion electronics and motor controllers to operate more
A heat treatment system for superconducting coil had been built at the Institute of Plasma Physics Chinese Academy of Sciences (ASIPP) for the central solenoid model coil (CSMC) for the China Fusion Engineering Test Reactor (CFETR). The CSMC is composed of Nb3Sn and NbTi hybrid superconducting coils. As Nb3Sn is a brittle material the technology of "wind and react" has been
Powerful new grade of Neodymium added to our magnet offerings A powerful new grade of Neodymium is now available at Dura Magnetics 55 MGOe Neodymium. As the strongest rare earth magnetic material available for commercial use N55M is about five- to six-percent stronger than N52 MGOe our previously highest available grade.

The outer ring the flange and the hub configure a three 3 sided circular shroud. The outer ring is contoured to have pockets recessed into the inner face of the outer ring parallel to the hub pockets to accommodate the fitting of magnets (7 8) into said pockets.
For the application of GTS a novel magnetic propulsion system is proposed which combines the outer rotor motor and MLS together as shown in Fig. 5. It consists of three parts (i) an inner stator (ii) an integrated rotating part (iii) a hollow translator moving back and forth along the axis direction. Due to the use of outer rotor topology

On the one hand the mutual inductance coefficient between the two coils is consolidated. On the other hand the leakage of the magnetic field is reduced. To calculate the coil magnetic flux linkage Fig. 1(a) shows a single-turn circular coil whose inner radius is R 1 outer radius is R 2 average radius is b and circular section radius is a.
A five-band tunable ideal terahertz metamaterial absorber based on subwavelength range is proposed. It consists of a reflective layer a dielectric layer and an absorbing layer consisting of an internal closed square ring and an outer open square circle. We have found that the five absorption peaks can reach more than 97 on average. Meanwhile in order to analyze the absorption mechanism we
Two stacked disks were designed. In a 1-mT 1-Hz applied field the SF of the 4-mm inner diameter discrete stack is 1.21 107 (140 dB) and the SF of the 20-mm inner diameter split stack reaches 3.44 104 (90 dB). It implies that the stacked REBCO disks have great potential for the application of high-efficiency magnetic shielding.

Jupiter which is a gas giant is the largest planet in the Solar System and also has the largest magnetic field. Its large magnetic field is the result of the planet s fast rotation which is equivalent to 9.8 Earth hours. However the magnetic field is not generated by Jupiter s inner core but by its liquid metallic hydrogen outer core.
