We are talking about a field,, this is an interesting area as to whether there is an "object" that is bound by mechanics or not.

If the field rate of change propagates at C for an instantaneous change in flux density then an inductor would see a rate of change of C.

That "feels" like a small change in flux density over a smallish inductance would still provide a large output.  This also conforms to all accepted formulas,, except for the instantaneous change of course which no formula covers.

I have bookmarked a few places so I can learn how to make a few electronic control circuits so I can play more precisely with what I am seeing and playing with.  I am a slow learner and have scrap parts lying around to make things out of,, so that will take a while

Right now I can somewhat control the rate of change in a sine wave as far as current goes,, how much it is passing, but I would like to be able to clamp that down a lot more and maybe even see if it will go so far as affecting the DC throughput as well.

Hey Webby1 - Ah I see what you mean: Electromagnetic Waves (Radio Communications)

Yes, these are at C, the speed of light. However, the simple old Coax Cable is a medium where C is slowed somewhat, C can be only 65% of the speed of Light or there abouts. This is different than Flux Lines as such, Near Field and Far Field stuff now...

Last kick at the can for the Ward force generator.

I made a new rotor as there was an indication from some that my cast iron shoes were a source of eddy currents and hence holding back the generator. The no load drag as measured on the RV was 62 and 67 watts previously.

A bit like comparing apples and oranges as the new rotor version weighs in with much stronger magnets. But it's drag on the RV comes in at 78 watts. So I am of the opinion that the cast iron was no problem. This design actually narrows up the "shoe" area and initial cogging is greatly increased.

However, a pleasant surprise in that the output nearly smoked my poor load resister! 

!080 RPM, 14.5 watts in for 11 watts out

2850 RPM, 14 watts in for 36.5 watts out!!!

And even better at higher RPM's,

The bottom line --- the total input was 174 watts for 36 watts out. (scooter motor)

So end of experiment.

Hi Ron, Awesome! Your machining skills are very admirable! I truly view workmanship of this quality with admiration!

Would you view this experiment as more than useful?

My wife always says, "what does it do?" and I say, "nothing, it was a learning experience!"


It answered my questions --- mission accomplished!


Thanks, to all of you

Energy stored inside an inductor's magnetic field is E=0,5xLxI^2

With certain value of current and inductance we have a certain amount of energy stored. If the same energy is discharged through higher L, won't discharging peak current (I)  be less than what we have used during the charging cycle? (I=sqrt 2E/L).   

This was a misconception. Sorry guys. We examine a system which gains energy during discharge. So if charging and stored energy equals E1=0.5LI^2, then discharging energy E2 would be E2>E1!!!

Having this in mind check again the terms of the equation and decide by yourselves what needs for this to be accomplished.

"Conventionality doesn't lay at present equations which describe physical laws. It only lays in our interaction as observers to the said equations which describe these laws..."
