31Magnetic field of celestial bodies — See also Earth s magnetic field The magnetic field of a rotating body of conductive gas or liquid develops self amplifying electric currents, and thus a self generated magnetic field, due to a combination of differential rotation (different… …
32Stellar magnetic field — A stellar magnetic field is a magnetic field generated by the motion of conductive plasma inside a main sequence (hydrogen burning) star. This motion is created through convection, which is a form of energy transport involving the physical… …
33Orders of magnitude (magnetic field) — This page lists examples of magnetic field B in teslas produced by various different sources. They are grouped by orders of magnitude, and each section covers three orders of magnitude, or a factor of one thousand. Note: Traditionally,… …
34A Dynamical Theory of the Electromagnetic Field — which was written in the year 1864, is the third of James Clerk Maxwell s papers concerned with electromagnetism. It is the paper in which the original set of four Maxwell s equations first appeared. The concept of displacement current that he… …
35Wide Field and Planetary Camera — The Wide Field/Planetary Camera (WFPC) (pronounced as wiffpick) was a camera installed on the Hubble Space Telescope. It was one of the instruments on Hubble at launch, but its functionality was severely impaired by the defects of the main mirror …
36Coriolis field — In theoretical physics a Coriolis field is one the apparent gravitational fields felt by a rotating or forcibly accelerated body, together with the centrifugal field and the Euler field. Contents 1 Mathematical expression 2 Mach s view 2.1 Is it… …
37Hubble Deep Field South — The Hubble Deep Field South is a composite of several hundred individual images taken using the Hubble Space Telescope s Wide Field and Planetary Camera 2 over 10 days in September and October 1998. It followed the great success of the original… …
38Relationship between string theory and quantum field theory — Many first principles in quantum field theory are explained, or get further insight, in string theory: * Emission and absorption: one of the most basic building blocks of quantum field theory, is the notion that particles (such as electrons) can… …
39Electric field gradient — Mathematically, the electric field gradient (EFG) is the hessian matrix (the matrix of the second derivatives) of the electrical potential V: :V {ij} = frac{partial^2 V}{partial x i partial x j}It is an important structural property of a… …
40block field — A thin accumulation of stone blocks, typically angular, with only rock fragments in the upper part, over solid or weathered bedrock, colluvium, or alluvium, without a cliff or ledge above as an apparent source. Block fields occur on high… …
