DIRAC`S DREAM: THE MYSTERY OF THE MAGNETIC MONOPOLE
... with charge q and with strength falling off with the squared of the distance. We would then expect a magnetic monopole to produce a “hedgehog” magnetic field B = rg2 r̂. A bar magnet looks like two such monopoles put together. However, bar magnets are secretly the magnetic fields generated by the sp ...

... X-line begins to move tailward. • Earthward of the X-line the plasma sheet thickens and strong earthward flows are observed. • As the X-line moves toward its distant location, the currents and aurora begin to die at the lower edge of the auroral bulge. This is the beginning of the recovery phase. • ...

Hall effect
The Hall effect is the production of a voltage difference (the Hall voltage) across an electrical conductor, transverse to an electric current in the conductor and a magnetic field perpendicular to the current. It was discovered by Edwin Hall in 1879.The Hall coefficient is defined as the ratio of the induced electric field to the product of the current density and the applied magnetic field. It is a characteristic of the material from which the conductor is made, since its value depends on the type, number, and properties of the charge carriers that constitute the current.
