On this page I enter into wild speculation mode on how this thing might perhaps be made to work… (other than surfing, I get much of my exercise by jumping to conclusions based on limited knowledge and data). The following pictures and text describe my speculations about how to time the energizing and power extraction of a MEG. You might want to look at JLN's MEG animation first.

The switches represent suitable electronic means (e.g. FETs) for switching the input power and loads, assuming that these switches can handle peak voltages and currents. The switch control means would likely be firmware running on an Atmel AVR series microprocessor which could handle the MEG frequencies and proposed algorithms nicely.

Starting state - magnetic flux is even all the way around the core, there is no change in flux occurring and so no voltages are induced in the load coils.

Input Energized - One drive coil is energized, directing the magnetic flux into the right half of the core. The other drive coil and the load coils are not connected, and so there is no back EMF to impede the magnetic flux.

Loads Engaged - The drive coil is disconnected so that it generates no back EMF. The load coils are connected. As the magnetic flux seeks equilibrium in the core, power is generated to the loads.

Other Side - The cycle is repeated on the opposite side by energizing the drive coil, waiting for the flux to shift, connecting the load coils, and then de-energizing the drive coil and letting the magnetic flux power the loads as it seeks equilibrium in the core.

Timing of the switching can be tuned to optimize results for the particular core material, magnet strength, and coil configuration.

The duty cycle of the drive coils is set so that they are on only for the amount of time needed to switch the unimpeded magnetic flux to the opposite side of the core. The load coils are switched on just before each drive coil is disconnected.

Load coils are switched out after they have extracted most of the power from the flux change, and the cycle is repeated.

I recognize that I still have much to learn about magnetic and electric fields. Please send me your critiques and comments to: creator@flyinghouse.com
