Two semi levitating ferrite magnets

Two semi levitating ferrite magnets

I stumbled upon this by accident when i did a magnetic experiment with magnets and a container.
 I made two design with magnets glued one in the container and the other one on the screw lit. When I brought the two design together I heard a click and saw two semi levitating ferrite magnets.

Needed:
Two round ferrite magnets with a diameter of around 3.5 - 4 cm and 2 to 3 cm in length
 I used 2 speaker magnets with a cover hole in the middle
Two neodynium ring magnets of about 1cm in diameter
Two round iron balls around 1 cm in  diameter
Two ferrite magnets with a small hole in the middle around 1.5 cm diameter
A container with a screw lid or a double bar platform with two platforms that can be brought together

First the big ferrite magnets on top of this the neodynium ring magnets on the neodynium ring magnets the iron ball slightly in the ring and on the iron ball the ferrite magnets with a small hole.
Both design should look the Same.

Important:
The Right magnets and iron ball
The Right build up
 Also important is that the Right sides of the magnets face up or Down
That the two design have the right distance from each other

I made it in 2013 but it went lost.

Update 22-08-2017
Three new and better sketches

First it looks like this, before the two magnets shift into another position

Update 2017 before 07-2017

3 sketches:

I will make 1 or 2 better and more precise pictures later
