Experiment with Magnets in Middle and Some Physics.mp4

The actual physics is much more complicated since you would need to sum the x and y components of the force vectors as they interacted and decreased when the magnet turns to align north but the end result is pretty close to the experiment taking into account the resistance from the water and the difficulty in releasing the boat without pushing it.

Something next to consider is what happens when the magnet is far from the center of the boat with a balance weight on the opposite side of the boat. That seems to be much more powerful.

Stay tuned:)
