Some articles on magnetic:

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 ...
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 the superconductor being so ...
Electric Violin - Pickups
... Electric violins commonly use either magnetic or piezoelectric pickups ... Guitar /coil type magnetic pickups require the use of violin strings that have ferrous (iron-containing, as in steel) metal wraps or cores ... A few single-coil guitar-style magnetic systems are available, The small body size and arced string arrangement of a violin limit the amount of space available for coil placement ...
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 ... (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 ...
Electrodynamic Suspension - Uses - Trains
... In EDS maglev trains, both the rail and the train exert a magnetic field, and the train is levitated by the repulsive force between these magnetic fields ... The magnetic field in the train is produced by either superconducting magnets (as in JR-Maglev) or by an array of permanent magnets (as in Inductrack) ... The repulsive force in the track is created by an induced magnetic field in wires or other conducting strips in the track ...

Famous quotes containing the word magnetic:

    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)
