J-shaped magnetic motor! Has someone ever tried this?

[Low-Q]

Hi

I just came over an idea I had several years ago, which I never had time to build. The idea is based on the fact that constant magnetized iron will repell an equal pole from a second permanent magnet (as normal) unless the distance between them are so close that the force in the attraction between the iron and the second magnet is stronger than the repell force. In a critical distance between them, there are neither repell- or attraction force.
Take a look at the picture below, and try to imagine how it works. The distance A, B, and C does not provide neither repell- or attraction force. As the blue pole in the laminated "J-rion" is weakest at distance A this distance is longer than B, and again distance C is shorter than B. At point D, magnet 1 are suddenly in a repell position because the distance is suddenly too far. The point of no return is passed in distance D, and this will make the rotor to rotate - thats the thaught anyway.

Hi Vidar,

How can you make the material between C and D suddenly get magnetized and repel without any outside manipulation? What is more, the repel action should suddenly "appear" when the rotor magnet in question is just passed that point. Otherwise it is a "sticky" point for sure.
I think the path between C and D points can be only gradually made to repel the rotor magnets arriving there and this is already enough to stop the rotor after an initial push is made on it as a start.
I may be wrong but this how I think it now.

EDIT PS: Have a look at the first picture at John Bedini site:
http://www.icehouse.net/john1/motor.html   because it is based on some similar balance of the magnetic forces you refer to, I think.

The link you refer to is not the same, but if the magnet was fully covered by iron, it would look more the same.
I once discovered that balancing attraction and repelling by placing a permanent magnet in right distance to a magnetized piece of iron did not make a sticky point. So I manually moved the permanentmagnet further out to the side where it came far enough out to be repelled, without sticking into anything. However this simple device I tested was repelling with equal force from any direction forcing the device to stop anyway. The J-shaped magnetized iron, I hoped to gradually keep the critical distance until it is "too late", and then the permanent magnet in the rotor kept going clockwise...

I probably have to do "something" in the gap in the J-shaped iron to prevent the oposite of sticky points

Hi Vidar,

Gyula is right. I also think it will do nothing, sorry. The sticky spot is there between C and D, and I can see no force in this design to overcome it. In fact it looks very similar to some already failed design.

Sticky points... With very easy words, When like poles are moving towards each other, and become closer to each other. They repel, they do not want to become closer. So they never will, unless you input some energy, but this is not the option you're looking for.

Yeah, always with the sticky spots.  That was my $50.00 magnet motor lesson. 

I am still waiting for Steorn to show us no sticky spots.  And waiting. 

Did I mention that I was WAITING?
