Simple electric motors

From the Russian site Zabatsay, some demonstration to build a simple electric motor, requires:

A Single AA battery
A couple of regular steel paper clips
Some sticky tape
Some enamelled copper wire or verowire
A knife or scraper

I don't know why it works properly with a DC power supply and no brushes.

I think it maybe to do with an irregularly formed coil so that the magnetic field is uneven and there can be an average force.
