Mystery Fireball Over Atlanta 6 December 2010
Posted by: Editor in Science, Video, Weird Comments Offcaptured a short video of a double-barreled ball of fire
falling from the sky.
So far, Police have offered no explanations as to what it could be.

conductor in response to a changing magnetic field. Lenz’s law
predicts that the current moves in such a way as to create a magnetic
field opposing the change; to do this in a conductor,
electrons swirl in a plane perpendicular to the changing magnetic field.”
magnetic field of the falling magnet; there is attraction between
the two fields. Energy is converted into heat. This principle is used
in damping the oscillation of the lever arm of mechanical balances.”

“A homopolar generator is a DC electrical generator that is made when a magnetic electrically conductive rotating disk has a different magnetic field passing through it (it can be thought of as slicing through the magnetic field). This creates a potential difference between 2 contact points, one in the center of the disk the other on the outside of the disk. For simplicity one contact point can be considered positive (+), and the other contact point can be considered ground or negative (- or 0). In general the 2 contact points are linked together as the armature. It has the same polarity at every point, so that the armature that passes through the magnetic field lines of force continually move in the same direction. The device is electrically symmetrical (bidirectional), and generates continuous direct current. It is also known as a unipolar generator, acyclic generator, disk dynamo, or Faraday disk. Relatively speaking they can source tremendous electric current (10 to 10000 amperes) but at low potential differences (typically 0.5 to 3 volts). This property is due to the fact that the homopolar generator has very low internal resistance.” [Wikipedia]
