Why the Virus Magnet Boat Really Works

A force couple is when two equal forces in opposite directions are separated by a distance. The resulting torque is one of the forces multiplied by the distance.
But the key thing is that a couple can only result in torque to make a body rotate around its center of mass no matter where on the body the force couple is.

So In this video a best theory is explained as to why the boat accelerates from only the forces of the compass.

Stay tuned:)
