swhich permanent magnet on and off

[Omnibus]

It would be interesting to see whether placing soft iron between a magnet spun by a DC motor makes a difference (produces more energy than the energy needed to spin the motor) when that spinning causes a magnet attached to a generator to spin. As the experiment is now, however, such conclusion (that spinning the primary magnet produces more energy in th secondary magnet) cannot be made with certainty.

What I learn so far is that ferromagnetic materials shield better.

I've remixed the video here

What do you think, is it more clear like this?

Nice remix Gaby 

Okay so let me get this right.

Take two motors and place a magnet on each.
Place a shield between the two with it closest to the primary.
Power primary motor up and spin primary magnet.
Secondary magnet will spin and play catch up.
Meaure output of Secondary motor?

Is this correct, or am I just not getting it?

Cheers

Left is a primary axle with a magnet on top. Right is a secondary axle with a magnet on top. If there was no shield the secondary magnet would rotate along with the primary 1:1 With the shielding placed as illustrated (close to the domain wall a bit towards the primary side) the secondary magnet is is disconnected from the primary 2 times per rotation.

While the primary is facing the shield with both it's north and it's south pole (it's side) there isn't any flux propagated beyond it. Here the secondary axle stops and waits for the primary to move beyond this point. The moment the primary has moved beyond 50/50 induction the secondary will leap over the gap and catch up. The catching up power comes out of the magnet.

I can leave the primary in any position and it will just stay there. It's merely pulling the secondary into it's mirrored position when facing the shield. Should not be hard to test.  Just remember to place the conductor closer to the primary magnet.

I would like to get some feedback on this.

Why is the magnet on the right rotating in 45 degrees - 135 degrees - 45 degrees - 135 degrees etc.? Shouldn't it be 45 - 45 - 45 - 45 etc. but slower than the magnet on the left side?

I have investigated this a bit. When the magnets are pointing same polarity towards each other, it's possible to balance the forces to zero in x-plane. If you turn each magnet 45 degrees, clockwise for left and counter clockwise for right, the metal shielding between them will be forced up or down, the attraction between the magnets and the metal shield is also encreasing rapidly.
To be short: There is sticky spots which will force the magnets to "rest" in one or more particular possitions, so the rotation is not possible to do without using energy.

The same will happen when the magnets are round.
