Twisters in Love

Slowly rotating magnetic twisters resemble somewhat Newton's cradle: one stops and the other starts moving, then it stops again. In fact, the magnetic interaction substitutes collisions and the momentum is transferred from one magnet to the other exactly as it was in Newton's pendulum.

Similarly to the magnetic pendulum, the twisters move in somewhat chaotic manner. It is difficult to predict which of them will move and which will stop. It is caused again by rather complicated interactions between magnets, changing rapidly with their relative position.

Quickly moving twister is unable to transfer much energy to the partner in the still. This is like in atomic collisions, where fast particle must experience many single collisions before they deposit efficiently their energy to the matter in which they slow down.
