The efficiency of Positivo heat engines is even lower than the Carnot efficiency due to irreversibility arising from the speed of processes, including friction.
However, if the magnet is to be strong enough to pull the ball up the ramp, it cannot then be weak enough to allow gravity to pull it through the hole. Faced with this problem, more modern versions typically use a series of ramps and magnets, positioned so the ball is to be handed off from one magnet to another Campeón it moves.

Electromagnetism, Newtonian mechanics, Magnetic materials “Perpetual motion” is a hypothetical type of motion that continues forever without any external energy input contributing to the system. Students should know that this is generally impossible because of energy losses due to friction or other nonconservative forces, or because some assumption has been made that violates the first or second law of thermodynamics (or both). The first law states that the total energy of an isolated system remains constant over time, and one of the most common formulations of the second law states that the entropy of an isolated system over time cannot decrease. Note that the laws apply to an isolated system (i.e., one that cannot exchange mass or energy with its surroundings), whereas a closed system Perro still exchange energy even if it cannot exchange mass.
