See attached drawing.
You should be able to figure this out yourself, but I will type operation information.
End caps are being drawn today. They keep the .005" air gap between the magnet poles and the bar surface.
Thanks,

Materials:
1018 steel 1" x 1" square, 4 bars
Magnets, 1" x 1" NIB Grade 48
End caps, 1/4" thick 6061 T6 Aluminum
End caps added
This is as simple as it gets.
1. Move magnets in Pseudo Solid fashion to the end position on the left as shown in the drawing. This is done with the bars closed together.
2. Notice that because the flux between the magnets is at the rotation axis that the bars can be opened with ease.
Open them about 8 inches.
3. Now move the magnets to the right to the ends of the bars in the Pseudo Solid fashion as shown in the drawing.
4. Now let the bars close and notice the attraction force at work as the bars close.
5. Restart the cycle.
Note: The magnets float between the bars due to a .005" air gap at each pole. Non-magnetic inserts maintain the air gaps. This causes the magnet to have equal but opposite forces on the magnets poles and allows it to move freely.
I would need to see this in 3D as my visualization skills seem to be lacking.
I am suspecting though, that leverage and work done over a long distance are being confused for great output than input.
As usual, I hope to be proven wrong. If it's really easy, a small motor will power the moment, which will power a large motor which does serious lifting work.
Please review this video and imagine a hinge in the middle of the bars length. It relates directly to this design.
Thanks,
Butch
