Is the Ex-PRESS Glaucoma Shunt Magnetic Resonance Imaging Safe?
Journal of Glaucoma, 2010Ex-PRESS mini glaucoma shunt is a miniature, stainless steel, nonvalved device used for the treatment of glaucoma. The purpose of this study was to evaluate the safety of the Ex-PRESS glaucoma shunt during magnetic resonance (MR) imaging.The effect of a magnetic field on the Ex-PRESS glaucoma shunt was evaluated in 4 scenarios.

On the Role of Magnetic Shunts for Increasing Performance of Transverse Flux Machines
IEEE Transactions on Magnetics, 2017This paper presents work completed in order to investigate the importance of magnetic shunts in transverse flux machines. Two types of transverse flux machines with different configurations were designed and tested in the laboratory. The first type of machine is a transverse flux generator with inner rotor. This machine was designed according to one of

Stray Losses in the Step of a Transformer Yoke with a Horizonatal Magnetic Shunt
IEEE Power Engineering Review, 1982The distribution of stray losses in the step of a laminated transformer yoke with a horizontal magnetic shunt is solved using a network approach. Total losses, maximum loss density, and leakage flux return along the yoke all vary with gap spacings between shunt and yoke.

IEEE International Digest of Technical Papers on Magnetics Conference, 2003
Summary form only given. The magnetic core of a transformer for welding devices has a moving magnetic shunt. The shunt can assume several different positions to modify the flux leakage values. These transformers are made to supply high current values: saturation of the magnetic core leads to strongly deformed voltage and current.

Effect of Magnetic Shunts on the Eddy Losses of a Transformer Tank
Advanced Materials Research, 2012This paper presents a 3D FEM computation model for a power transformer structure, where several conductor disks in series are used to constitute each winding, this is different from the normal cylindrical shape models. Base on such model the simulated ohmic losses in windings can be the same as that of measured.

Cardiac pacemakers in magnetic fields of a shunt reactor at a 400 kV substation
International Journal of Occupational Safety and Ergonomics, 2015The use of cardiac pacemakers (PMs) increases in Western countries. The aim of the study is to investigate cardiac pacemakers (PMs) using a human-shaped phantom in magnetic fields of a shunt reactor at a 400 kV substation. We performed seven PM experiments using a phantom. Two locations close to the shunt reactors were chosen.

Theoretical treatment of internal shunt protection for superconducting magnets
Journal of Physics E: Scientific Instruments, 1971Considers the theory of internal protective shunts and switches used to limit the maximum temperature rise when a large high-current density superconducting magnet quenches, whilst operating in the persistent mode. The shunts can induce more even heating and dissipation, thus avoiding hotspots.

MAGNETIC CIRCULAR SHUNTS FOR STRAY FLUX IN POWER TRANSFORMERS
2021Energetski transformator jedan je od ključnih elemenata elektroenergetskog sustava te o njegovoj pouzdanosti i učinkovitosti ovise pouzdanost i učinkovitost čitavog sustava. Stoga je pri projektiranju transformatora bitno minimizirati vjerojatnost kvara, ali i gubitke.
