well. I'll try. :)

p.s. And the ripple does not crawl from your power supply?
Is the voltage filtered well?


A crystal could replicate any "Hetrodyne" effect from the transformer. The critical point is that the oscillation dies off without the magnets attached! It wouldn't cost anything to feed the electromagnet an oscillating signal. The signal is not oscillating the stator. Take away the magnets and the force of the oscillation vanishes!


When we add magnets and reinforce any oscillation, including A.C., it does nothing to increase the consumption of power required by the electromagnet to maintain it's own field.

Let's say we place 2 cube magnets in opposition polarity on the legs of a Washtub stator then run a milliamp A. C. current into the coils?

We will see more power from a "Bloch Wall" oscillation then inputted. Remove the magnets and the electrical input would be completely force less. The cost to oscillate the Spring by electrical power without the magnets with a force equal to the magnets would equal the gain. The gain can be out putted through a linked stator and secondary coils.

this kind of a.c. transformer can deliver lower voltage ac.

I see the inscription 15 volts AC. Where does the direct current come from?

On a direct current it did not work for me. But on a variable, a really permanent magnet gives an increase in vibrations. If you use alternating current in the coil. :)

And with which polarisation relationship,kolbacict ?
Permanent magnet NS to electromagnet N or S ?
How works a shock wave lithotripsy machine ? Ultra sonic : frequency ? sound waves up to Theta

@Kolbacict,

Can you please try and upload a video of "A permanent magnet increasing A.C. current vibration"? Believe it or not, this video would set a new high water mark!

Nothing special !

We have motion-to --signal converter : Henry telegraph device ( + Morse-alphabet),but also static generator developped by Graham Bell.
Is this device not a signal-to-motion converter ? It seems !

"When a permanent magnet is brought near to an electromagnet energized by AC,
the following things can happen (depending on magnitude of AC and inertia of permanent magnet):
If the frequency of AC is low it may be able to produce vibration in permanent magnet If the frequency of AC is high,
no vibration would be produced due to inertia of permanent magnet".

I agree.
My coil is powered by a sine wave, approximately 80Hz.

@Kolbacict,

I managed to detect the increase in speed over the background music in your video. I have a question: How are the magnet fields directed when the acceleration begins? Is the "Neutral Plane" directed towards the motor with the N S fields up and down?

You succeeded at showing a really cool A.C. magnet effect. George Chianiotakis demonstrates this effect with a "Reed Switch", but all his videos are pulsed D.C.

I want to ask if you can please redo the video with the background music turned down? This is an important video, you need to improve the quality to make the "Overunity" effect stronger to the viewer.

Imagine a washtub stator with NS magnet cubes, one on each leg. How much of the permanent magnet field changes leg position along with the A.C. signal? Your demonstration suggests that the A.C. field can dovetail and oscillate more then it's own flux by scarfing additional flux from the hand held magnet; The A.C. acting like a transistor gate for the PM fields you position in adjacency?

Matching the vibrator A.C. current Hertz with the ring frequency of the magnet generates the resonance that equals a large permanent magnet field shift.

@Kolbacict,

We get the "Advantage of the Sum" when we match the A.C. frequency of the vibarator to the ring frequency of the permanent magnet. The electro-magnetic field adds together with the permanent magnet force in resonance!

When the coil is disconnected, the oscillations stop.  When shorting the coil too.  I think if i pass direct current through the coil result will be the same.

I don't know if we can hope for any results from that approach.

An 80Hz sine wave can very easily be generated with an online sound generator and amplifier. I plan on using the software on two Washtub stators and magnets.
 
Nunez runs Rodin Coils with this trick. This could easily generate the 6x power increase Brad achieved.

Is it possible  more about Marco Rodin’s coil? Why did it make a noise ;) a few years ago, and then went into oblivion?
