A young man from Italy shows us some omopolika motor with batteries and magnets, moving up in foil. For the construction of a omopolikoy motor, need a simple AA battery and two coin-shaped magnets.

If we say that the South Pole of the magnet is the North S N, the construction should be done in the following way to work:
S-N battery N-S
N-N S-S battery
i.e. at both ends of the battery to pole itself is. The motor must then be placed onto a conductive surface, as a foil.
