Rotating magnetic field — A rotating magnetic field is a magnetic field which changes direction at (ideally) a constant angular rate. This is a key principle in the operation of the alternating current motor. In 1882, Nikola Tesla identified the concept of the rotating… … Wikipedia
field — /feeld/, n. 1. an expanse of open or cleared ground, esp. a piece of land suitable or used for pasture or tillage. 2. Sports. a. a piece of ground devoted to sports or contests; playing field. b. (in betting) all the contestants or numbers that… … Universalium
Electromagnetic clutch — Electromagnetic clutches operate electrically, but transmit torque mechanically. This is why they used to be referred to as electro mechanical clutches. Over the years, EM became known as electromagnetic versus electro mechanical, referring more… … Wikipedia
Electromagnetic projectile devices (fiction) — Electromagnetic projectile devices which use electromagnetic means to accelerate solid materials, such as Kinetic energy weaponry, Gauss guns, Mass drivers or Railguns are often used in fiction, especially science fiction.Realism of… … Wikipedia
Field coil — A field coil is a component of an electro magnetic machine, typically a rotating electrical machine such as a motor or generator. A current carrying coil is used to generate a magnetic field. Magnetic fields require a continuous circuit, thus… … Wikipedia
Rotating wave approximation — The rotating wave approximation is an approximation used in atom optics and magnetic resonance. In this approximation, terms in a Hamiltonian which oscillate rapidly are neglected. This is a valid approximation when the applied electromagnetic… … Wikipedia
Magnetic field — This article is about a scientific description of the magnetic influence of an electric current or magnetic material. For the physics of magnetic materials, see magnetism. For information about objects that create magnetic fields, see magnet. For … Wikipedia
geomagnetic field — Magnetic field associated with the Earth. It is essentially dipolar (i.e., it has two poles, the northern and southern magnetic poles) on the Earth s surface. Away from the surface, the field becomes distorted. Most geomagnetists explain the… … Universalium

Earth's magnetic field — Computer simulation of the Earth s field in a normal period between reversals.[1] The tubes represent magnetic field lines, blue when the field points towards the center and yellow when away. The rotation axis of the Earth is centered and… … Wikipedia
Wide Field and Planetary Camera 2 — The Wide Field and Planetary Camera 2 (WFPC2) is a camera installed on the Hubble Space Telescope. It was installed by servicing mission 1 (STS 61) in 1993, replacing the telescope s original Wide Field and Planetary Camera (WF/PC). It was used… … Wikipedia
