I've done a fair amount of work for the past few months trying to get a MEG to work. This was all based on the "law" that basically states that electrical current is induced through a coil by varying the magnetic field through it's core. This is what is claimed to cause the transfer of electrical energy through a transformer. I have come to realize that this law is not accurate.
I have built and tried dozens of different physical and electrical configurations of the MEG with no success whatsoever. I almost got to the point that I thought a permanent magnet was fundamentally different from an electromagnet, until I tried the electromagnet in the same place as the PM and it didn't work either.
I can switch magnetic flux from a permanent magnet through a coil all day long but it simply does not produce any electricity. I can see the switching pulse induced into the load coil, but the magnet makes absolutely no additional difference. I get the exact same waveform and power readings when the magnet is removed. I've tried alternating polarities across a coil, bucking arraignments, series additive and subtractive coils, only using one polarity or the other and it all works as though there is no magnet in the circuit whatsoever. It's very strange.
I've used very short pulses to switch a magnet across a coil. According to academia, the magnetic current should continue to polarize the core once the pulse has ended and produce current in the windings. This does not happen.
I have come to realize, after only 3 or 4 months of banging my head against the wall, that magnetic current moving through a core alone does not induce electrical power in the windings. I proved this to myself by taking a powerful magnet and connecting it across a coil with large bars of steel. I then pried off the bars and let them snap back on to the core while monitoring an analog volt meter across the windings. No matter what I did, I could not induce even a minuscule deflection of the needle, even though I was on the lowest millivolt setting. This simple test showed me that the MEG will never work in it's most common configurations
This begs the obvious question: Why does a transformer work and a MEG doesn't? In the MEG there is a lack of a critical change that needs to take place in order to induce current into the windings. I suspect that it is the phase relationship between the B and the H fields. In a permanent magnet these forces are in phase. This would account for the fact that one cannot wrap a PM with wire and get DC out of it.
In a transformer, there is a continual phase differential between the primary and the secondary. There is also a phase differential between the voltage and the current. As long as this phase differential exists, power can be generated in the secondary. If it were only the change in flux through the core that produced voltage in the secondary, a square wave could not pass through a transformer undistorted, which is not the case.
When a magnet is moving by a coil, the relationship between magnetomotive force and magnetic current must be altered in a time sense. How exactly this happens is unclear to me at this point. However, finding a way to alter the phase relationship of a PM in a circuit, without moving it, is the next step. Bearden says he's done it with a Metglass core, which I don't have access to. However, I do have some magnetite sand, among other things, that I'm going to mold into a core and see what happens. Composite cores tend to act like capacitors, as the gaps between the particles will store energy instead of passing it straight through like steel cores will. Perhaps this will help alter the phase of the magnetic forces as they pass through.
I assume magnetic force and magnetic current are similar to their electrical counterparts. As such, they would be susceptible to unequal propagation delays through certain materials and configurations. Finding and testing these materials and configurations will most likely lead to some progress in getting the MEG to produce some power. We shall see...
