DYNAMO® - The Kinetic Flashlight!
The Physics of DYNAMO®
|
|
In 1831, Michael Faraday discovered how to transform mechanical energy into continuous
electrical energy by moving conductors through magnetic fields, thus laying the
foundation for today's technological society.

|
Fascination's DYNAMO® Flashlight is based on this discovery.

The first dynamo was comprised of a rotatable copper disc placed between the poles
of a horseshoe magnet. One wire of the current indicator (galvanometer) was connected
to the axle of the disc, and the other was connected to a sliding contact on the
edge. When the disc was rotated, the needle of the galvanometer moved in one direction
and remained in that position as long as the disc whirled.
