Russian magnet motor

[2tiger]

Hello Stefan
Well I will try with a better draw,?cause my english is not yet good enough for complex explanations.

On experiment A now you can see where the kitchen balance is. The balance is connected with the plastic axel to the sliding Neo and by pushing on it, it shows me the repulsion force 300g to 3,2Kg, depending of the distance between the two magnets.

In experiment B you install the knife in the gap it will stuck instantly to the lower Neo.
Now you push down the balance (Pos. 1). You will see that the balance shows you roundabout 400g, till the sliding Neo stucks to the knife too.
Next step - with the same balance you try to push the knife (Pos. 2), that is "caught" by the two Neos and the balance will show you about 300 g till the knife overcomes the friccion in that "magnet-sandwich".

I hope this will help you understand, what I mean.

I think that this motor setup seems to look very promising.

Hi
If U don?t have the ressources (kitchenbalance, piece of wood, etc.), you can try this and feel the difference with your fingers.

A. Try to remove the knife up, away from the magnet -> high force  =  attraction force (doesn?t matter if it is an other magnet or any other piece of ferromagnetic material)

B. Try to move the knife sidewise -> about ten times lower force!

I cannot say why, but I?m sure that this smal force is only necessary to overcome the fricction between the magnet and the knife. This would mean there are forces in front of and behind the magnet that cancel each other out.
If we minimize the fricction, perhaps with s stripe of teflon, one on the magnet and another one on the knife, and the force we need to push the knife over the magnet goes down, then my assumption could be confirmed.

Unfortunately I?m now constructing myself a house and don?t have much time to test this out.
If anyone of you is going to test this, please report us the results.
Thanks.

Hi
Now I found the answer to my question myself.
First, forget my prediction that there are forces canceling each other out.....! 
On the pic you can see scan from my good, old physics book.

In this experiment there are 10 N pulled by 0,2 N even with friccion. So the force you need is 50 times lower!
And you can easily compare this with the pullout from my knife away from the magnet.

Let us say the knife has a weight from about 100 g. Now take a magnet, glued it on the table and let the knife stick to it. When we now messure the weight of the knife against the table, there will be about 3,2 Kg (attracion force from the magnet) plus the 100g of the knife  =  3,3 kg * 9,81= 32 N.
And this is the weight we have to pull, but with 50 times lower force (32N / 50 = 0,64 N) we will only need 0,64N to do this.

The next step would be to install the knife on a steeltrack with steelrolls in order to decrease the glidefriccion.
The glidefriccion between steehl and steel has an index-nr. of 0,002.
So Fglide = 32 N * 0,002 = 0,064N. At least we would need to pull the knife out of the magnet-sandwich with only 0,064 N so that the repelling force (between the magnets) can take effect =32N. And I?m only talking about a Neo-magnet cylinder with 10mm diameter and 5mm thikness.

Waiting for replies.

Hello!
You argue correctly. But there are some features which do not allow to create the ready engine easily.
At me already almost all is ready, but I move to other city. Therefore works stop for one year.
In Russia it is a lot of oil, therefore such engines are not necessary for it.
Yours faithfully, Anatoly.

Hi 2Tiger,
this is interesting !
If you really have measured the forces with your kitchen balance,
then can you calculate how much energy
the upper magnet does, when you pull the knife out ?
As Energy is force x distance, how many mm or inches does the upper
magnet move, when you pull out the knife ?
Yes, it is the same principle as Anatoly uses in his motor
and I hope he can get his motor soon to work.
It probably really depends on the thickness of the knife plate.
Many thanks.
Regards, Stefan.
