Where the OVERUNITY using INDUCTION COILS comes from (eg Joule Thief)

Brad,

I think that in your test you should use a lower capacitance for the faster pass of the magnet.

I think that you should use all 3 values for both the slower speed pass and the higher speed pass.

More data points are a good thing

No,because we want to keep the coil peak voltage the same,which will leave only an increased value of current that is the cause of the larger cap having the same EMF value across it.

The parameters of my test to be carried out

Test will be carried out in two parts
Part one
1-A magnet will be pasted across an inductor at a set constant speed
2-The distance between the magnet and inductor will remain unchanged in both parts of the test.
3-The inductor will retain the same peak value voltage across it for both parts of the test.
4-The capacitor will be charged in the first half of the cycle,and discharged(shorted)in the second half of the cycle,so as each cycle starts with a discharged cap.
5-The capacitor value for the first half of the test will be 220uF
6- 5 captured cycles will be recorded,and averaged out--the recording will be the voltage potential across the 220uF cap. From this we can calculate the average energy received from the coil for each single pass.

Part two
1-This part of the test is much the same as part one,but where we change the 220uF cap out for a 470uF cap.
2-The speed at which the magnet passes the inductor will be increased until such time as the peak voltage across that inductor is equal to that of what it was in part one of the test. This way we know that an increased voltage potential(EMF)across the inductor is not responsible for !a yet to be determined! outcome of the test.
3-Once again,5 captured cycles will be recorded ,and averaged out,so as we can calculate the energy received from the coil for each cycle.

From this test,where we have kept the EMF value across the inductor the same throughout each of the two test's,we can then arrive at 1 of two conclusions

Conclusions

1-If in each of the two test's,the value of the stored energy in the two cap's calculates out to be the same,then we can conclude that passing a magnet over a coil faster,dose not increase total current value delivered from that inductor.

2-If we end up with more stored energy in the 470uF cap,where we moved the magnet across the inductor faster,then we can conclude that you do get a higher total current value if you move a magnet across an inductor faster.

If anyone can see a flaw in these test parameters,please feel free to point them out.

Tinman I love your test. You are my kind of experimenter....  - simple and clear...

If you are going to move the magnet faster I will still suggest you try it with a smaller cap,,

A smaller capacitance at a higher voltage might surprise you with more energy stored, most likely not,, but I thought I would mention it.

Of course the test could fall on its face with a cap that is to large to start with,, I was surprised at how small the single pass cap needs to be with some of the testbeds I have played with.

If then moving the magnet faster and filling a smaller cap up to a higher voltage has more energy stored within the cap,, then what?
I figure you will get there anyway,, seems like the logical thing to do as well.

I wonder if there is a "virtual" resistance value for a cap to a voltage\amperage\Coulombs kind of thing.

Once again Webby,the larger cap is to keep the voltage across the coil at the same value we had in the first part of the test.

If the voltage potential remains the same,what would be needed in order to fill a larger cap,in a shorter time period of time,to a voltage of what the smaller cap had?.

The answer is simple.

If we make the magnet pass really slow, its like a tornado with 10mph winds
