- First Electric Motor
In 1821 the conversion of
electrical energy into mechanical energy in
the form of a motor was first accomplished by
Michael Faraday with the invention what we
today call a Homopolar Electric Motor. A
Homopolar Motor is quite simply a wire
suspended above and in contact with a pool of
mercury with a par magnet in the center, when
a current was sent through the wire rotated
around the bar magnet. The motor was never of
any practical use but did confirm that current
flow through a wire causes a circular magnetic
field.

- Faraday Cage
A Faraday cage is a cage made
out of any conducting material like iron or
steel. The cage transfers electromagnetic
radiation around the exterior of the cage
effectively canceling out the charge inside of
the cage. In short a Faraday cage is basically
a large conducting sphere which keeps charge
circling around he exterior of the cage.

This invention works on the same
principal as the
Homopolor motor, but in the opposite direction. Where
the motor converted electrical energy into
mechanical energy
the Faraday disk converted mechanical energy to
electrical. By having a stationary magnetic field
in the form of a bar magnet Faraday
was able to produce a current in a copper disk by
rotating it between the pols of the magnet and
effectively changing the magnetic flux through the
disk.
This is the same
principle that modern magnets operate on today
