The Magnet Recognition Program is a recognition program operated by the American Nurses Credentialing Center that allows nurses to recognize nursing excellence in other nurses. It is considered the highest recognition for nursing excellence. [1] The program also offers an avenue to disseminate successful nursing practices and strategies.
Ferrite (magnet) A stack of ferrite magnets, with magnetic household items stuck to it. A ferrite is an iron oxide -containing magnetic ceramic material. They are ferrimagnetic, meaning they are attracted by magnetic fields and can be magnetized to become permanent magnets. Unlike many ferromagnetic materials, most ferrites are not electrically ...
Description. An electropermanent magnet is a special configuration of magnetic materials where the external magnetic field can be turned on and off by applying a current pulse. The EPM is based on a common magnetic configuration called magnetic latch (right picture). A general example of this configuration assembly is built by a permanent ...
Magnetic hysteresis occurs when an external magnetic field is applied to a ferromagnet such as iron and the atomic dipoles align themselves with it. Even when the field is removed, part of the alignment will be retained: the material has become magnetized. Once magnetized, the magnet will stay magnetized indefinitely.
A single-molecule magnet ( SMM) is a metal-organic compound that has superparamagnetic behavior below a certain blocking temperature at the molecular scale. In this temperature range, an SMM exhibits magnetic hysteresis of purely molecular origin. [1] [2] In contrast to conventional bulk magnets and molecule-based magnets, collective long-range ...
A magnet is a material or object that produces a magnetic field. This magnetic field is invisible but is responsible for the most notable property of a magnet: a force that pulls on other ferromagnetic materials, such as iron, steel, nickel, cobalt, etc. and attracts or repels other magnets. A permanent magnet is an object made from a material ...
A quench is an abnormal termination of magnet operation that occurs when part of the superconducting coil enters the normal state. This can occur because the field inside the magnet is too large, the rate of change of field is too large (causing eddy currents and resultant heating in the copper support matrix), or a combination of the two. More ...
Programmable magnet. Programmed magnets, or polymagnets are magnetic structures that incorporate correlated patterns of magnets with alternating polarity, designed to achieve a desired behavior and deliver stronger local force. By varying the magnetic fields and strengths, different mechanical behaviors can be controlled.
