Although it negates the possible theory of Perpetual motion, it does not rule out the magnetic machine formed by the experimental arrangement of permanent magnets. If permanent magnets are properly arranged through experiments and can cause the machine shaft to move under the repulsion or attraction of the two stages of the magnet (magnetic force doing work), it is entirely possible to form a magnetic motor.

Nowadays, there are many methods to achieve the manufacturing of magnetic motors, and many people have already achieved success. However, this kind of magnetic machine does not belong to "Perpetual motion", because it is constantly consuming magnetism and will always stop doing work at one time, so the magnetic machine needs to be magnetized every other period.

For example, the Sel machine is also a type of magnetic machine, and there have been continuous imitators making similar Sel machines. Official research institutions in the United States and Russia are also replicating and confirming the principle of the Sel machine (there are public experimental reports on the Internet). But their principles and material structures are different. So Ser machines are a type of high-speed magnetic equipment, and their structural principles are not unique, but they are all achievable energy devices.

Magnetic force will gradually demagnetize when doing work, and the magnetic field generated by permanent magnets will gradually weaken, especially for repulsive magnetic motors. Just like using a strong magnet to repel a weak magnet, the magnetism of the weak magnet will reverse to correspond to the strong magnet (being magnetized). When the magnets do work, their magnetism will gradually affect each other, and the magnetism will inevitably be consumed.
