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 one of a family of iron oxide -containing magnetic ceramic materials. 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 ...
Magnetism is the class of physical attributes that occur through a magnetic field, which allows objects to attract or repel each other. Because both electric currents and magnetic moments of elementary particles give rise to a magnetic field, magnetism is one of two aspects of electromagnetism. The most familiar effects occur in ferromagnetic ...
A rare-earth magnet is a strong permanent magnet made from alloys of rare-earth elements. Developed in the 1970s and 1980s, rare-earth magnets are the strongest type of permanent magnets made, producing significantly stronger magnetic fields than other types such as ferrite or alnico magnets. The magnetic field typically produced by rare-earth ...
In condensed matter physics, the term geometrical frustration (or in short: frustration[1]) refers to a phenomenon where atoms tend to stick to non-trivial positions [citation needed] or where, on a regular crystal lattice, conflicting inter-atomic forces (each one favoring rather simple, but different structures) lead to quite complex structures.
This model shows how the different forms of power affect one's leadership and success. This idea is used often in organizational communication and throughout the workforce. "The French-Raven power forms are introduced with consideration of the level of observability and the extent to which power is dependent or independent of structural conditions.
The shape of the magnetic fields of a permanent magnet and an electromagnet are revealed by the orientation of iron filings sprinkled on pieces of paper. A magnetic field (sometimes called B-field[1]) is a physical field that describes the magnetic influence on moving electric charges, electric currents, [2]: ch1 [3] and magnetic materials.
Coercivity, also called the magnetic coercivity, coercive field or coercive force, is a measure of the ability of a ferromagnetic material to withstand an external magnetic field without becoming demagnetized. Coercivity is usually measured in oersted or ampere /meter units and is denoted HC. An analogous property in electrical engineering and ...
