Complexity of magnetization and magnetic simplification
We use the complexity=volume (CV) prescription to study the effect of a magnetic field on the computational complexity for states in the gauge theories dual to two different gravitational models. In one of these theories the complexity increases with the intensity of the magnetic field, while in the other a more interesting behavior is discovered ...

Impulse Magnetized Magnetic Screws [PDF]
This paper is an investigation in the performance of two types of magnetic screws (MSs). The first is the magnet to magnet and consists of permanent magnet (PM) nut and PM screw and the second is a magnet to reluctance and consists of PM nut and a double-start reluctance screw.

A case of ingested multiple magnetic beads: the importance of suspicion based on medical history [PDF]
We report a 33-month-old boy who presented to the emergency department with mild periumbilical abdominal pain lasting for 3 days. A plain abdominal radiograph showed 7 magnetic beads, which were located possibly in the small intestine without a free air.

On the Effects of Lamination Artificial Faults in a 15 kVA Three-Phase Transformer Core
Cutting and punching of the steel used in power transformer core may cause edge burrs. This, along with the degradation of the lamination insulation, can lead to interlaminar short circuits.

Characterization of Permanent Magnet Magnetization [PDF]
The performances of electrical machines highly depend on the behavior of materials, such as steel, copper, and permanent magnet. This paper focuses on permanent magnets whose magnetization must be precisely known. Thus a non-destructive approach which includes a combination of experiments and inverse problem, using the magnetostatic moment method, is ...
