Permanent magnet synchronous motors are efficient motors, which have widespread applications in electric industry due to their noticeable features. One of the interesting applications of such motors is in underwater vehicles. In these cases, reaching to minimum volume and high torque of the motor are the major concern. Design optimization can enhance their merits considerably, thus reduce volum...

Background: Magnet therapy has been used increasingly as a new method to alleviate pain. Magnetic products are marketed with claims of effectiveness for reducing pain of various origins. However, there are inconsistent results from a limited number of randomized controlled trials (RCTs) testing the analgesic efficacy of magnet therapy. This study aimed to evaluate the safety and effectiveness o...

We present a case that encouraged us to revisit the management algorithm in single magnet ingestion [1]. A child had undergone a double-barrel sigmoid colostomy for anorectal malformation during neonatal period, with a plan for staged surgical repair. At four years of age he presented to the surgeon after ingestion of a single small magnet. The magnet was visible in the epigastrium on radiograp...

MRI is a widespread and greatly helpful diagnostic tool, yet its use on cochlear implant patients is restricted by the presence of an inner magnet. We report on a case of magnet dislodgment after 1.5T MRI in a 31-year-old female with a Hi-Res 90K cochlear implant. In this case, it was possible to implement an alternative, totally noninvasive approach based on an external manual repositioning ra...

We developed, built and beam tested a novel, compact, in-vacuum undulator magnet based on an adjustable phase (AP) scheme. The undulator is 1 m long with a 5mm gap. It has a pure permanent magnet structure with 24.4mm period and 1.1 Tesla maximum peak field. The device consists of two planar magnet arrays mounted on rails inside of a rectangular box-like frame with 156 mm x 146 mm dimensions. T...

The Next Linear Collider (NLC) uses a damping ring for the electron beam, a pre-damping ring and a main damping ring for the positron beam to reduce the beam emittances. The requirements of the main damping ring kickers are to bend a 2 GeV beam by an angle of 2 mrad over a length of 1.2 m. This results in a required field of 139 G. The magnet aperture is 30×30 mm. The predamping ring kicker req...

A prototype 2-Tesla superconducting transmission line magnet for future hadron colliders was designed, built and tested at Fermilab. The 1.5 m long, combined-function gradientdipole magnet has a vertical pole aperture of 20 mm. To measure the magnetic field quality in such a small magnet aperture, a specialized rotating coil of 15.2 mm diameter, 0.69 m long was fabricated. Using this probe, a p...

An achiral molecular square and a chiral chain composed of cyanide bridged Fe(III) and Ni(II) ions were prepared, and they act as a single molecule magnet and a chiral single chain magnet, respectively.

A new direct-drive, out-of-vacuum synchrotron injection septum magnet has been built at the Advanced Photon Source to replace the existing eddy-currentshielded, in-vacuum magnet. We describe the design, assembly, construction, and measurements.
