conclusions we found the magnetic field assistant device to be an accurate, radiation-independent jig for close passing of guide wire after close reduction of femoral fracture. it can reduce the need for radiation during placement of guide wire for closed intramedullary nailing of the long bones. more studies are required to improve and evaluate the technique and equipment. results outcomes of ...

A 2D analytical method for magnetic vector potential calculation in inner rotor surface mounted and surface inset permanent magnet machines considering slotting effects, magnetization orientation and winding layout has been proposed in this paper. The analytical method is based on the resolution of Laplace and Poisson equations as well as Maxwell equation in quasi- Cartesian coordinate by using...

Highlights: The modified Millard technique, including the Tennison triangular flap, is effective in preventing vermillion notching and reducing scar complications cleft lip repairs. technique addresses concerns related to compromised tissue nostril deformities, leading improved appearance functionality. Scar thinning techniques separate nasoraphy contribute enhanced aesthetics optimal healing A...

Fast-ramping superconducting (SC) accelerator magnets are the subject of R&D efforts by magnet designers at various laboratories. They require modifications of magnet design tools such as the ROXIE program at CERN, i.e. models of dynamic effects in superconductors need to be implemented and validated. In this paper we present the efforts towards a dynamic 2-D simulation of fast-ramping SC magne...

In this note theory and measurements of the effect of the eddy current in the laminations on the magnet field will be presented. The theory assumes a simple solenoid–type magnet with laminated iron core and ignores the end field effect. The measurements were made on the input voltage and current, and the dipole component of the magnetic field in the middle of the magnet bore. The amplitude and ...

This paper presents a new trapped-field magnet made of second-generation high-temperature superconducting (2G HTS) rings. This so-called ring-shape 2G HTS magnet has the potential to provide much stronger magnetic fields relative to existing permanent magnets. Compared to existing 2G HTS trappedfield magnets, e.g. 2G HTS bulks and stacks, this new ring-shape 2G HTS magnet is more flexible in si...
