now that is cool ...   just waite till he figures out the speed part of it

BARBI not digging your humour kind of condisending  IS this the time ?will this be it? from divine inspiration to working device [again]almost 100 yrs later? the table is set can this be it? a Feast? Chet

nice graphics GK,  and nice joke barbosi  LOL


@ all,

Pay attention, this is a new theory on the hubbard coil.    I've been thinking how do people arrive at these things?  What do they think about?  If the theory we come up with is too complex perhaps it's wrong.   Hubbard did not just throw together eight coils and the central coil together just for fun and realized something is happening, in other words, I believe people build something because they have an idea in mind, but the results might just surprise them.

So what did Hubbard have in mind?   Did he really think about the 8 electromagnets firing in sequence?   Maybe, but I think he might have had something simpler in mind.  Something more related to the knowledge of the day, something having to do with basic TRANSFORMER PRINCIPLES.

Here's the basics:

1)  Changing magnetic flux through a core wound with a coil will induce a voltage as  V = n d phi/dt, where 'n' is the number of turns of the coil

2)  Two coils on the same core, and overlapping, share all the same flux, so V1 = n1 dphi/dt,  V2 = n2 dphi/dt, and if we rearrange we get   V1 = V2 * (n1/n2)

3)  Transformers are assumed to conserve power so V1 * I1 = V2 *I2,  and based on the previous equations another equation can be derived  I1 = I2 * (n2/n1)

However,  if we have a third coil in proximity to the two closely coupled coils,  this coil will have a weaker coupling to the other two coils.   So,  consider this scenario based on the diagram below, assume n1=n2

1)  We energize L1 with a voltage V1, and since L2 is closely coupled, we have V1 = V2, and I1 = I2, we expect no losses in current or voltage if we hook these two coils together, which seems like a dumb thing to do cause it's so simple.

2)  However, now consider that the flux influences the center coil and induces a voltage in it.   The flux does not have to go through the core it can avoid it on the outside, but the magnetic flux will seek the path of least resistance, and it's this tendency that generates our free energy.  In other words we are letting the magnetic flux expand SIDEWAYS. 

3) The voltage generated in this coil we will use as the signal source for the first two coils hooked together, so now  we have a third voltage that tries to drive the two to resonate and amplify the voltage and current. 

So,  V1 = V2, but we are adding a V3, so V1 is actually V2+V3, but V2 is equal to V1 so it too must be V2+ V3, but we are adding V3  so we have V1 =V2 + V3 + V3, and so on, so do you see where this is going?   It's an amplifying loop, that stops when the resistance of the wires overpower the voltages and currents.

Anyway, this was a bit of hand waving for me, I'll try to do more rigorous calculations in the future...the important point is to remember that the sideway expanding flux might give rise to free energy.....

EM

P.S.  I encourage you guys to ponder this aspect of two coils tightly coupled so V1 = V2,  and then consider part of the flux partially penetrating a third coil that feeds it's voltage back to one of the first two.  It's one of those scenarios that boggles the mind, an iterative sort of a dynamic that takes some thought.  this could be what drove Hubbard to design his coil.  Or it wasn't,   LOL, but it's a damn good experiment to try out.  You see the center coil can resist the flux and the flux can go on the outside just fine  (but higher resistance) so the tendency of the flux to spread out is what really accounts for the extra energy if any.

I added the second diagram.  Notice the resistor R.  It has a voltage drop across it equal to V3, so then V1 = V2 is satisfied.   So when you hook a load to the output that is less then the value R,  the currents will INTENSIFY, to match the new conditions.   by the way, this is an AC system, flux needs to change else it doesn't work.  I'm getting all excited here folks,  any body seeing what I'm seeing?

Howdy Y'all,

EMDevices, hmmm... AC Transformer math?  Hmmm...  I think I have heard something about that...
That inductive coupling that you are examining is happening with all nine coils simultaneously.  It would be a very complex equation to figure out how energizing one coil effects all the others.  What matters is you add some energy to this thing and the ripples go everywhere...

Got Core?

Satisfaction of curiousity is the reward for unhindered adventurism.
I am building this next stage with my PMHs as the core. Thrown together? Absolutely. I got results everytime.
Only those who take chances see the rewards.

Yep. Ring the bell. Keely tapped the energy off the water hammer.

We 'shall' be known by our works.

-giantkiller. The combinations are getting fewer and all advice is good.
