El campo vectorial de magnetización M representa la fuerza con la que una región de material está magnetizada. Se define como el momento dipolar magnético neto por unidad de volumen de esa región. La magnetización de un imán uniforme es por tanto una constante del material, igual al momento magnético m del imán dividido por su volumen. Como la unidad SI del momento …

Where this Specification uses technical terminology, defined in the Glossary or otherwise, that refer to enabling technologies that are not expressly set forth in this Specification, those enabling technologies are EXCLUDED from the Scope of this Specification. For clarity, enabling technologies not disclosed with particularity in this Specification (e.g. semiconductor …

Electric fields are caused by electric charges, described by Gauss's law, and time varying magnetic fields, described by Faraday's law of induction. Together, these laws are enough to define the behavior of the electric field. However, since the magnetic field is described as a function of electric field, the equations of both fields are coupled and together form Maxwell's …

Maxwell's equations, or Maxwell–Heaviside equations, are a set of coupled partial differential equations that, together with the Lorentz force law, form the foundation of classical electromagnetism, classical optics, and electric circuits.The equations provide a mathematical model for electric, optical, and radio technologies, such as power generation, electric motors, …

Electrodynamics is the physics of electromagnetic radiation, and electromagnetism is the physical phenomenon associated with the theory of electrodynamics. Electric and magnetic fields obey the properties of superposition.Thus, a field due to any particular particle or time-varying electric or magnetic field contributes to the fields present in the same space due to other causes.

What if we built our communities around places? As both an overarching idea and a hands-on approach for improving a neighborhood, city, or region, placemaking inspires people to collectively reimagine and reinvent public spaces as the heart of every community. Strengthening the connection between people and the places they share, placemaking refers to a collaborative …

Species were unique lifeforms. They were generally divided into three classifications based on their level of sentience: sentient, semi-sentient, and non-sentient. There were over 20 million sentient species known to the galaxy. Sentient species were sometimes erroneously referred to as races, which more accurately referred to groups or subspecies within a species. The five …

In the developmental biology of the early twentieth century, a morphogenetic field is a group of cells able to respond to discrete, localized biochemical signals leading to the development of specific morphological structures or organs. The spatial and temporal extents of the embryonic field are dynamic, and within the field is a collection of interacting cells out of which a particular …

For antennas shorter than half of the wavelength of the radiation they emit (i.e., electromagnetically "short" antennas), the far and near regional boundaries are measured in terms of a simple ratio of the distance r from the radiating source to the wavelength λ of the radiation. For such an antenna, the near field is the region within a radius r ≪ λ, while the far …

The Dark Eye (German: Das Schwarze Auge, lit."The Black Eye") is a German tabletop role-playing game with a high fantasy theme created by Ulrich Kiesow and launched by Schmidt Spiel & Freizeit GmbH and Droemer Knaur Verlag in 1984. It is the most successful role-playing game on the German market, outselling Dungeons & Dragons.Many years of work on the game have …
