Exploiting BACK EMF from pulsed DC transformer

[leofree1980]

Hi
What do you think about this transformer?
Transformer with Embedded Magnets to redirect Magnetic flux so No CEMF against  no degradation of source energy coil.

It's a transformer with losses.
Welcome to the real world.

To expand on what Dave said.

When you put power into the transformer, the magnets will resist some of the current. When you try to draw power out of the transformer, you draw power from the coil and the core, but not the magnets.
Transformers always have, and always will be AC devices, pulsed DC is converted to AC, use a oscilloscope to look at the waveforms.

Hmm... troll or spam (or nutter) warning.  Same post appears on All About Circuits*, EDABoard and DutchForce, and probably others.  New registered user, single post, no follow-ups yet.

*Their moderators probably deleted it already.  It shows up on Google search results at this moment, but the post is 404.

All of these are just "drawing" right ? I mean like picture as in cartoon for enjoyment ?

I’m definitely not a transformer expert but it seems like the OP assumes that static magnetic fields will somehow lessen losses in the multiple core transformer scheme simply because the input is pulsed DC. 

If I remember correctly, a transformer works via the changes in magnetic fields generated by the primary winding(s). I somehow fail to see how magnets in the core will bias or enhance any magnetic changes and most likely will lessen the efficiency; especially with all of the added cores and windings shown in the picture.  Maybe the OP can enlighten us further.  Ferrite transformer cores are cheap on ebay and a relatively inexpensive diamond blade can cut them to pieces for the magnets to be glued in place.  A relatively cheap mock up could show the unlikely merits or failure points.  (Maybe even turn normal transformer losses into over unity gains???)

Many of these 'over unity' experiments rely on measuring power in pulsed circuits. What the experimenters fail to realise is that this is not easy to measure accurately. A frequent misconception is that because they are using true RMS meters, that VxI will always give power.   

The simple, reliable test would be if they can power the device from its own output (minus batteries) If they can do that, then I'll sit up and take notice. 

Though, there is one 'magnet motor' that runs for several minutes on the charge in a 10uF 25V capacitor. Not over unity though, just a very efficient design. I thought that was a cool bit of engineering work.

Hello
Thanks for your suggestions
Let us consider a simple version of this device:

The problem is, what you've produced is just a cartoon illustration that probably you've dreamed of.

Show the real working photo of "real life" prototype & measurements results.

Please stop wasting time and bandwidth with this idea. It can't work because it doesn't adhere to the law of physics which says energy has to be preserved. If you are going to measure your setup using the right tools then you'll find you get less energy from the output then you put into it due to losses. Energy cannot magically appear!

Leofree 1980 should be encouraged to build prototypes of his designs and make a few youtube videos explaining his theories.  Then get some true believer patrions to help fund further study and pay for some nice toys test equipment.  After awhile this learning experience may evolve into something useful; or at least a basic understanding that physics and electricity are basically the same but from different perspectives.
The possibilities are almost limitless; for instance add another magnetic loop and arrange them in a circle, stonehenge style so the magnetic fields don’t radiate out the ends.  Then put some permanent magnets that rotate around an axle in the center and a couple of more coils phase shifted and reinvent the brushless DC motor or maybe something like this:

Has anyone seen these:

Hello
Thank your for your analyses
I have not the necessary materials, but il will experiment this with the minimum and the simplest design like this:

[Red Squirrel]

What happens if you connect the output to the input?

COP must >> 1

Nope.

Try building it. If you really believe in it, you should not have a problem paying a pretty buck for the equipment and materials.
