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...

It has been known for some time that high-temperature superconductors (HTS) are critical for the construction of NMR magnets generating 1 GHz and above. Such systems generally require an HTS insert to be placed in the inner high-field region of a low temperature superconducting (LTS) magnet. Among the problems in the presently available HTS technology are splice resistance and index dissipation...

day, however, the ophthalmoscopic picture was substantially altered. At the former site of the foreign body there was now only a fine hazy spot of exudate, the foreign body was now further forward in the eye, and could be seen to move in response to the magnet to nasal and temporal sides in turn. Two further days were spent in attempts at extraction by the electro-magnet, but without success. F...

Following the construction of two hybrid magnets, we intend to build up a third hybrid magnet which will produce about 30 T. A prereacted multifilamentary Nb Sn conductor will be employed for the 12 T superconducting part of the hybrid. As a first step for the project, we have designed, constructed and tested a magnet which consists of 14 double-pancakes made of a prereacted multifilamentary Nb...

background: lidocaine is a local anesthetic and antiarrhythmic agent. there are reports on accidental and intentional cases of poisoning following injection of lidocaine while rare are the fatal cases realized after oral ingestion of lidocaine. suicidal poisoning with lidocaine pharmaceutical formulations is rare since no pharmaceutical dosage forms for oral use are available except gels and sp...

background: formalin is an aqueous solution of formaldehyde. it is a protoplasmic poison and causes coagulation necrosis and tissue fixation. case: a 19-year-old girl was brought for autopsy to the mortuary of jss medical college, mysore. conclusion: formalin is an unusual poison to be ingested for suicidal purposes due to selective availability and its strong taste and odor.

introduction: ingestion of a foreign body is a common problem among all age groups. most of the foreign bodies in the pharynx are usually lodged at the level of cricopharynx. the diagnosis is based on history, clinical, and radiological examination. most foreign-body ingestions are accidental, but there may be contributory factors such as mental disorder, alcoholism, and prison incarceration. t...

The effects of high temperature homogenization and low temperature annealing treatments on the microstructure and magnetic properties of sintered magnets of an Nd17Fe76.5B5Cu1.5 type alloy have been investigated. The microstructure of the as-cast alloy, consisted of three phases including a Nd2Fe14B1 (2:14:1- type) matrix phase Cu-containing Nd-rich Phase and Free α-iron. The as-sintered magnet...

A strong interaction between light and a magnet can produce a hybrid system with energy levels distinct from either the light or the magnet on its own. In this “strong coupling” regime, quantum information can be easily transferred from the light to the magnet and vice versa. This feature could be useful in quantum information technologies or as a way to use one component (say, the light) to pr...
