External Magnetic Fields

Some articles on external magnetic fields, magnetic, magnetic fields, magnetic field:

Condensed Matter Physics - Experimental - External Magnetic Fields
... In experimental condensed matter physics, external magnetic fields act as thermodynamic variables that control the state, phase transitions and properties of material ... Nuclear magnetic resonance (NMR) is a technique by which external magnetic fields can be used to find resonance modes of individual electrons, thus giving ... NMR experiments can be made in magnetic fields with strengths up to 65 Tesla ...
Magnetic Dipole
... A magnetic dipole is the limit of either a closed loop of electric current or a pair of poles as the dimensions of the source are reduced to zero while keeping the magnetic moment constant ... It is a magnetic analogue of the electric dipole, but the analogy is not complete ... In particular, a magnetic monopole, the magnetic analogue of an electric charge, has never been observed ...
Faraday Effect - Mathematical Formulation
... Formally, the magnetic permeability is treated as a non-diagonal tensor as expressed by the equation The relation between the angle of rotation of the polarization and the magnetic field in a ... to L-rotation (anticlockwise) when the direction of propagation is parallel to the magnetic field and to R-rotation (clockwise) when the direction of propagation is anti-parallel ... By placing a rod of this material in a strong magnetic field, Faraday rotation angles of over 0.78 rad (45°) can be achieved ...
Flux Pinning
... Flux pinning is the phenomenon that magnetic flux lines cannot move (become trapped, or "pinned") despite the Lorentz force acting on them inside a current-carrying Type II superconductor ... phenomenon cannot occur in Type I superconductors, since these cannot be penetrated by magnetic fields (Meissner–Ochsenfeld effect) ... The natural magnetic waves that bend around and pin the superconductor in mid space also break into millions of ultra-thin lines and each one carries a flux quantum caused from ...

Famous quotes containing the words fields, external and/or magnetic:

    It is not those who till the fields who eat fine rice, nor those who rear the silkworms who wear fine silks.
    Chinese proverb.

    Nature predominates over the human will in all works of even the fine arts, in all that respects their material and external circumstances. Nature paints the best part of the picture, carves the best of the statue, builds the best part of the house, and speaks the best part of the oration.
    Ralph Waldo Emerson (1803–1882)

    We are in great haste to construct a magnetic telegraph from Maine to Texas; but Maine and Texas, it may be, have nothing important to communicate.
    Henry David Thoreau (1817–1862)
