Is this waht you asking?

Is it possiable to get electricity from the magnetic field its self with out puting any energy into the device?

No, what I think he is asking is this:

Can you use a dipolar dynamo design and simply turn one rotor magnet around so that it no longer creates a flux path between the magnets?

well, I guess that depends on what type of dynamo/generator you are using.

If you're using the most simple dynamo it would be a loop of wire which rotates along the side axis (the 12 o'clock - 6 o'clock line) while a magnetic field lies perpendicular to the axis (so that would be the 3 o'clock - 9 o'clock line). If you were to turn one magnet around, the induced current would still flow from the axis to the 'top' of the loop on one side (say the 'left'), but on the other (say the 'right') the induced current would also flow from axis to 'top', which would of course result in a zero current between the two wires at the axis (where one would normally get the current in such a design). So in this design it would result in a zero induced current.

But there are also generators that use a different setup. Versions of the Muller generator for example, use magnets that all face the same way, and a wheel with coils that spin so that the cils are aligned with the magnetic fields periodically, and the variations in flux that the coils 'see' induce a current.
So here there we have a different setup...

But in any case, the induction of current in a conductor moving through a magnetic field is obviously always related to the spin contained in that field.
And a field has poles. If there were not two opposing poles, there would not be a magnetic field, and induction effects would be zero.
I think.

Not as far as I know of...

I guess the closest thing to extracting energy from a magnetic field directly in the sense that you mean, would be the MEG http://jnaudin.free.fr/meg/meg.htm ...
But in fact you do need to pump energy into the activator coils to get output from the collector coils. The output is supposed to be higher than the input, and the source of the magnetic 'flux' that is transformed is in fact the permanent magnet in the center. Last I heard they were still trying to close the loop as it apparently worked fine when the input and output circuits were completely seperated, but when the loop was closed it did not... And they've been quiet and secretive for a while now, probably because they have applied for a patent and are awaiting the outcome.
So still needs some input to get something out.
