Free Energy will change the World - Free Energy will stop Climate Change - Free Energy will give us hope
and we will not surrender until free energy will be enabled all over the world, to power planes, cars, ships and trains.
Free energy will help the poor to become independent of needing expensive fuels.
So all in all Free energy will bring far more peace to the world than any other invention has already brought to the world.

I have just carried out some testing in regards to a ferrite or PM core being placed near an air core coil.
As you will see in the scope shots below,no effect what so ever takes place when either a ferrite or PM core is placed near a pulsed air core coil/inductor. I even went as far as placing the ferrite core,and the PM on top of the coil it self,and no change at all was noted on the scope traces.

Some info regarding the tests
The CSR value is 33 ohms-->high so as i could detect even the smallest of changes in current and voltage/current phase angle.<--no changes were noted.
The coil is about 1 cubic inch box shape,and has a resistance of 145 ohms.
Duty cycle is 50%.
Supply voltage is 12 volts.
Ferrite rod used is 19mm x 25mm.
PM (also a rod) is also 19mm x 25mm.
Both keeper and PM were placed 2mm away from coil end<--so very close to coil.

Note:-even at this low power input,i could feel the PM vibrate/oscillate quite strongly,but nothing from the ferrite keeper.

The tests were carried out at 10Hz,100Hz,and 1KHz-as shown on each scope shot below.

It is clear from these test that there is no difference or change at all in regards to current,voltage, or phase angle change between current and voltage regardless of weather there is no keeper in place,a ferrite keeper in place,or a PM keeper in place

The tests are well intentioned enough, but if you actually want to know, then you will need to make some adjustments:
1) You need to set the time scale on your oscilloscope according to the L/R time constant of the circuit.
2) You need to make sure that you do not hide the circuit behavior with too large a value current sense resistor.
3) You need to make sure that you do not hide the circuit behavior with a current sense resistor that has too long of an L/R time constant of its own.
4) You need to make sure that you don't introduce distortions that hide the circuit behavior by the instrument settings, such as using AC coupling where it is not appropriate.

Fixing 1) is pretty easy.  Just start speeding up your sweep rate / reduce the timescale until you can clearly see the exponential current rise caused by the applied voltage step.   It is this current rise that you want to see.

Fixing 2) is a matter of picking a current sense resistor value that is less than 1/10th the winding resistance of your coil.

Fixing 3) is a matter of using a current sense resistor that has an inductance:   Lsense_resistor <=  0.1 * Rsense/Rcoil * Lcoil.  If you don't already have any non-inductive current sense resistors, they are available from Digikey for about $1. each.

Fixing 4) is a matter of making sure you understand how to use your test equipment.  Avoid AC coupling especially for pulses that last longer than 1ms.

I can not go much lower on the CSR,as i am already at 2mV per division on my scope,and that is as low as it go's.If i lower the CSR value,then we will not see much at all in the way of a trace across the CSR.
AC/DC coupling in this case made no difference at all,and i left it as AC so as we could see any noise change within the current trace. At 1KHz,we have only a 500uS pulse,and we still see no change.

Edit:
Tomorrow i will up the input power,lower the CSR value(with a non inductive CSR),and switch back to DC coupling.
We will then carry out the same test,and post results.

Tinman,

What MarkE said...

I will add:

We are only interested in what occurs during the rising and falling (changing) portions of the waveform.  The scope's horizontal timebase (and V sensitivity) should be adjusted to display those portions of the waveform with as much clarity/resolution as possible.  We only need to see one complete cycle (or a bit more).  If necessary, use magnification to further resolve rise/fall edge details.

Consider your scope as being somewhat similar to a microscope,  You need to focus on and adjust the magnification and position so that what you are attempting to visualize is resolved with maximum resolution.

Apparently we need to discuss AC versus DC coupling again.  The "tilt" in your CSR waveforms is due to your use of AC coupling.  They will square up if you switch back to DC coupling.  AC coupling is used for removing a larger DC (and LF) component from a waveform so that the vertical sensitivity can be maximized to display any AC signal that may be riding on that DC voltage.  Most of the time your scope should remain DC coupled.

Wind is nothing more than solar energy.  Unequal heating and cooling of the earth's surface creates wind.  Wind is just another delivery vehicle for solar energy. Gravity is a closed system and no additional energy can be extracted from it and be made to perform work.

Bill

  I doubt that Tesla would agree with your evaluation.
   Gravity is caused by the Earth's Vortex, combined with our Solar Vortex, and Galactive vortex. All taking in and constantly pulling Aether in from the primordial soup, which some call "nothing". 
Not a closed system at all. 
  And solar energy is caused by What? Is that a "closed" system, as well? That can't be taken from?

  Anyways, no need to expound on it, quoting from the current false information that our scientists are telling us. I've heard it all before.
