Russian magnet motor

@Antoly:
What is still missing ? Better magnets ?

The magnet with the special sizes is necessary for me.
Therefore it should be ordered. One magnet do for a long time.

Hi Anatoliy,
I am very sceptical about your design and here is why:
In your diagram for component number 3 it says Ferromagnetic shield. Correct? If I got this bit right then I don't see how the motor will work because ferromagnetic materials are attracted to magnets. This is the very reason they are able to shield the magnetic field. They shield by interacting with the field. And interaction with the field causes them to be attracted. This is a problem because in your design you have a piece of ferromagnetic material lets say steel. The steel is basically between two magnets. The steel is pulled away from the magnets by the spring. This will require a lot of energy from the system, because if the spring is strong enough to pull the shield away, the repelling force of the magnets will not be strong enough to stretch the spring again. The repelling force between the two magnets will always be smaller than the attraction force between the magnets and the steel. The reason for this is because the steel is always closer to the magnets than the magnets are to each other. And as we all know the closer you go to a magnet the denser the magnetic flux becomes. I think this is the main problem - the steel is always closer to the top magnet than the bottom magnet is because the steel is between them and is exposed to much stronger field than the bottom magnet. As with hundreds of other mechanisms I've seen on this forum, if you use a material which shields magnetic field but is not attracted by the magnet, then your motor will work.

This motor design is one of the few designs I've seen that may actually work, provided you manage to make the magnetic screening a pure modulation, thus extracting minimal energy from the downward motion. The screening material between the magnet should NOT interact with the magnetic fields in any way other than to diminish its effect. If this design is to be successful at all you cannot have significant work associated with the insertion/exsertion of the screening material per "combustion" cycle. Using ferromagnetic materials is not the way to go here because you'll experience substantial force when moving the metal screen in and out of the gap.

As far as I can tell, the biggest hurdle with this design is the magnetic screening material used during the upward cycle, but other than that we have a classic combustion engine. We need a material that does not interact with the magnetic fields but merely functions as a barrier. Also, the screening material should be as thin as possible to allow very close proximity of the magnets, thereby maximizing the "combustion" pressure. Would a thin sheet of high density lead work?

Keep up the good work!

...we have a classic combustion engine.

Worth noting that typical internal combustion engines are 30% efficient (mostly heat loss, but the mechanical losses are pretty stiff too).

There is no such thing as a shielding material that is NOT ferromagnetic.
