Title: Magnetic field Propulsion - propagation delay
Post by: Blainiac on February 21, 2013, 02:24:04 AM
Okay, let me start this by saying that this device would not violate any laws (that I know of).  Momentum is conserved, since the magnetic field in this example would carry momentum in the opposite direction as well.  I've looked around the net to see what a magnetic field looks like as it propagates free space, but I couldn't find anything...

Imagine a simple case:

There are two powerful electromagnets in space, connected by some mechanical rod or something.  Let's name them A and B.  There is also a distance between them as well, D.  We assume that nothing travels faster than light, including disturbances in magnetic fields.


Imagine both electromagnets are off initially.

1) So, let's say we turn electromagnet A on.  A magnetic field is created around it.  We only allow it to be on for as long as it takes the magnetic field information to reach electromagnet B.  As soon as electromagnet B is able to 'see' electromagnet A is on (the delay would be the time it takes light to cross the distance between them), we turn it on.

2) At the same time we turn electromagnet B on, we turn the other one off and open the circuit to prevent it from being influenced again by changing magnetic fields.  At this point, electromagnet B is repelling off of the magnetic field created by electromagnet A, and pulling the whole craft in the repelling direction.  After acceleration, turn electromagnet B off.

3) The magnetic field is distorted, and this information travels back to the first electromagnet (A), but since it was off and disconnected, the magnetic field passes through it, carrying momentum in one direction, as the craft goes the other.

4) Rinse and repeat.  Maybe a few times a second?  Maybe much more frequently?


The whole operation of this craft depends on the propagation delay of a magnetic field.  Since we can turn electromagnets on and off, we can make it 'seem' like an electromagnet is still on, even if it is not.  The turning on and off would have to be controlled independently and fine tuned, since information can't travel between the two electromagnets faster than the distortion itself.

What do you guys think?  Plausible?  I know it wouldn't work if the electromagnet that created the first magnetic field disturbance was left on.

Simple and outside the box.  Imagine being able to stack the effect.  If only it were that simple!  Read the snippets of Tesla's "Solidification of the aether" that remain in the public domain.  Having witnessed exotic flying craft that 'squirt' about as if to thumb their noses at inertia itself, both in day time at close range and night....I'd say that something profoundly simple, yet difficult to control is certainly going on! (which would explain a lot regarding the ufo explosion in the nineties, ie. advent of microprocessors)  An account from one of my personal experiences is contained here: (

Did you ever get a real response to this question? I have been wondering the same thing for years actually and I cannot find an answer. I have a half dozen examples of things you can do with the propagation delay of a magnetic field.

Hey jdlewis!

I didn't see this reply since I haven't been on these forums in a long time, so sorry for the delay.  I have looked around online recently (due to remembering about the idea), but haven't found anything that resembles it.  It seems like such a simple idea to test out, and I completely agree that there are a few interesting things that you could do if something like this was possible (flying cars, spaceships, etc.).

Recently, I was thinking of simplifying the whole arrangement to see if any detectable force in one direction could be attained.  I was thinking of replacing one of the electromagnets with a parabola-shaped piece of diamagnetic material (like Pyrolytic carbon) with one electromagnet in the focal point of the parabola shape.  This would *hopefully* maximally reflect the electromagnetic field in a direction.

When the electromagnet is on, it's connected to the electromagnetic field that is propagating at the speed of light from it, so that any interactions with the field will eventually interact with the electromagnet.  When the diamagnetic material repels the incoming electromagnetic field, the electromagnet will be turned off and prevented from interacting with the electromagnetic field somehow, so the field will pass by without cancelling out the momentum gained by the parabola.  After an amount of time, the process is repeated!  :)

I think the hardest things would be building an electromagnet that could be turned on for only a very brief time and back off again so it doesn't interact with the reflected electromagnetic field.  Unfortunately, I don't know enough about building coils or anything, so I'm not sure how to proceed without help from someone with experience.  Maybe a powerful square wave signal?  I don't know.

It seems so simple to test out.  I'll try to include some drawings soon (edit: added!).  Thanks for replying after all these years!

Don’t take this in the wrong way, I’m not arguing against relativity

But if we examine the flux-domain of Michael Faraday
We see there is no dimension of time.

There is a second in the Maxwell, cm-gram-second
cm cancels in the Gauss, second cancel from the electric field
We are left with gram

Let’s go the other way
There is seconds^2 in the Weber kg-meter^2/second^2/Area
meter^2 cancels out in the Tesla, time cancels in the electric field
and we are left with kg/area

We see that time does not matter in the magnetic domain.
It is only a matter of mass, or density.

The magnetic field is instantaneous
it does not “propagate”, except as a factor of the electric field propagation
which does involve time.

Using electromagnets, the delay of the field is determined by the velocity of
the electric-flux.
This is dependent upon resistance, which is dependent upon temperature.
In the cold of space, operating temperature of the coils is low.
R is low, so we’re talking about a high frequency

Let’s take a period of time, we’ll call it T
And we can say that half of T, the electric field travels to the other coil
and half of T, it returns.
So the second coil would also have a period of T.
But out of phase 180-degrees.

But what happens to the electric field?
We see that at all 3 nodes of interaction, there is no electric field.
The potential is 0, and no electric field exists between the two coils.

There will occur, in space, an electric field, of 4 polarities, who’s motion is that of the ship.

Adjust the timing or phase of either field in either direction, and we have an electric force
the electric force is not tied to the source, but the magnetic IS!
so this device can be made to work, but not by magnetism.

By electric field.

Like the brown-craft/iono-craft propulsion/asymmetric capacitor
The charged aluminum is attracted to the electric field, not the wire, so it propells.

If we did this with a magnet tied to a coil, the magnet would pull towards the coil
Not the space the coil sits in. So the craft is not propelled.

Did you take a look at the Jefimenko's equations?
I am also looking for a software capable of simulating it...In case you find something useful, please let me know.
