Hubbard coil

[EMdevices]

Don't underestimate the "FORCE",  the magnetic field when "cornered" will "bite" and "snap" with violent fury !!!      



>>>While the device has been patented, the claims for it are so broad that Hubbard says he does not feel safe in making public his secret.  In general, he says, it is made up of a group of eight electro-magnets, each with primary and secondary windings of copper wire, which are arranged around a large steel core.  The core likewise has a single winding.  A coil thus constructed, he says, is lifeless until given an initial impulse.  This is done by connecting the ends of its windings for a fraction of a second to an ordinary[two words unreadable R.L.R.] -ing circuit, he says.<<<

The following figure shows the typical model of a transmission line, with the inductance and capacitance per unit of length (lossless so no resistance included)

Then we see a coupled transformer line, which is what the Hubbard coil could be utilizing (I don't believe the radium story, it's a cover up I think)

But the real intriguing phenomena is to realize what happens when the magnetic field is "cornered" or "trapped".   In other words,  consider an inductor that has current flowing through it.   If that current is suddenly interrupted (and really it can't)  the voltage spikes really high. 

The underlying phenomena here is really deeper.    A current through a coil sets up a magnetic field, and if the current is interrupted, the magnetic field will collapse.  However, as it collapses, it induces a voltage (electromotive force) in the wires IN SUCH A DIRECTION TO KEEP THE CURRENT FLOWING SO THE FIELD GETS MAINTAINED.  It's a type of "inertia".  In other words, this is Lenz's law that says the behavior is such as to resist the change.

But now consider an inductor, with current flowing in it, suddenly connected to another inductor (and disconnected from it's powering source or battery).   Do you realize that now we are bringing two forces against each other?  One inductor wants to have current flow at some value, and the other inductor wants to stay at zero current.     It's like the scenario of INFINITE FORCE TRYING TO MOVE THE IMMOVABLE ROCK. 

So what gives?    This is where it gets interesting, very interesting.....  we can also spice up the problem and say, let the coils not even have the same number of turns, or not even be close to each other so they are not coupled magnetically, and then later consider different levels of coupling of the coils, etc....

I'll tell you what happens,  there is inter winding capacitance, so when the coils are switched together in a closed loop (assuming no magnetic coupling)  the coil that had a current and magnetic field will have it's magnetic field collapse rapidly depending on the design of the coil and the separation distance of the turns.  Why?  Because there is capacitance between the windings (usually small).  The Voltage at the terminals will skyrocket  according to the well knows formula   V = L di/dt, where di/dt is the rate of change of the current, and L is the inductance.  (we don't to complicate things, but the other differential equation for a capacitor will actually give us a partial diff. eq. that we can solve, but we'll end up with the self oscillatory frequency of a coil, etc..)   

However,  at the same time,  the other coils with a zero current through it will see this spike in voltage at its terminals which will start to drive the current through it at a rate equal to  di/dt = V/L   (just rearranged the same equation) , 

so these two coils will perform an exchange of magnetic energy with quite a snap, and huge voltage surges, which indicates that the coils need to be designed well and single turn preferably.

The other case when the coils are close together and magnetically coupled gets more interesting and has a few permutations, as in, how do you hook up the coils, to have the fluxes aiding each other or bucking?   more to come.....

P.S. Another way to visualize the Hubbard drum, is to visualize springs inside and compressing one spring and letting go will cause ripples that persist for a while.  The way the coil is configured, the power is extracted only on the outside coil by a type of dragging effect, that's why it's claimed to be a pulsing DC type of current (or voltage).  Other modes of resonance are certainly possible, and it should be noticed his device has an iron drum comming between the inside coils and the outer winding, so you can see why that is, it's to close the magnetic flux path from each inner coil through a sector of this outer iron pipe.   A motorized version of the Hubbard coil can also be created.  Place a long axial magnet on the inside of the drum and rotate it.  On the outside of the drum wrap the coils and you will see a voltage.   Even though there is no apparent flux cutting occurring in this scenario,  the A-potential (or the magnetic vector potential) is the answer.  V=u dA/dt, and the A potential certainly changes with the motion of the magnet.  This type of induction is more of a dragging sort of a concept.  Charges are pushed ahead of the A field disturbance.

Looks very much like Leedskalnin's PMH. Also needs just an tiny bit of initial energizing. What happens if you take 3-4 plain PMH devices and put them in such an arrangement that blocks current flow within each? I myself pretty sure an aetheric vortex will be created around these devices - it's about the only way to allow for current to continue flowing. It's a "least difficult route" of a kind.

@EMD,
I am glad you mentioned the nix on the radioactive material. I thought the radioaction would be a possibilty to start the tuning forks ringing. Now I think differently. No more flirting with disaster.

Also,
Take a 3 or 4 segment, 3 layer TPU and connect the layers with caps like the LMD. It works up instead of horizontally. Current on 1st layer, diamagnetism on 3rd layer. And the added feature is the ring configuration.

Also, you have a ring. That is what Stan Deyo shows in his design.
