Science Challenge: Prove these magnets won't move

kmarinas86

1) An electromagnet with north up
2) A paddle
3) A permanent magnet (magnet A) positioned north down on top of the left side of the paddle
4) A permanent magnet (magnet B) positioned south down on underneath of the right side of the paddle

Reasoning) If the electromagnet is turned on from the position seen in the video - http://www.youtube.com/watch?v=YHHab4c4hsk, magnet A will rise and magnet B will fall due to the laws of magnetic repulsion and attraction. When the paddle turns over 180 degrees, magnet A will be where magnet B was and magnet B will be where magnet A was.

Additional information) The magnetic field lines of the two magnets feed into each other, creating what is called, in some engineering circles, a "magnetic circuit".
