M.E.G replication attemp

[patmac]

Ooops sorry I don't know exactly what is the inductance on secondary, but the coil is near to be secondary on Naudins rep, >1 Henry. Capacitor coupling to match resonance is a interesting thing, my idea with wall transformer is to step down and recharge a possible battery used like input. Maybe I need calculate the inductance on the coil first to buy the exact capacitors.

Well, if you have some capacitors or some hundred pF value at hand, you can check resonance by removing the varistor and connecting known values of caps in parallel with the secondary and sweep the input frequency to look for voltage maximum output on the scope. No need for running on 24V input, maybe 10-12V DC would be enough.

If you wish to step down the output voltage by a wall transformer, then you need to reduce the output voltage to as low as the wall trafo's primary designed to and that is either 120V or 240V AC at 50 or 60Hz. and you have around 6kHz output freq... Maybe you have to build a dedicated transformer with ferrite core like the ones used for line output transformers in old CRT monitors/TV sets.

Looking forward to building this

Hi all,
Ive been reading this thread intensely and look forward to putting together my replication of the M.E.G . I have ordered the core from Metglas and am awaiting its arrival from India. Evidently the cores are now made there. Until then I wait.

Really good, MetGlass is a requirements to get good results, the ferrite cores present losses when output voltage is high spark goes to the core.

MetGlass is the only core material where the magnetic transistor effect is present, so in the ferrite core I can say output is identical with or without permanent magnet.

Hi Patmac,

It is good you are already aware of this because as a test I wanted to suggest you take out the magnet(s) from the core and see any change in the output...

On the Metglas core, there is an update to an earlier Metglas core 'treatise' from Cyril Smith here in two parts, probably you have read them:
Some MEG throughts by Cyril Smith and Some MEG throughts by Cyril Smith

Cyril has been a member at the Megbuilders yahoo group where several MEGs have been built during the years from 2001 to 2007 including both ferrite and Metglas cores. Still, nobody managed to get extra output wrt the input during that long time. It is a mistery, why... Recently the yahoo group has been closed:

Thank you for this Gyula,
I have read through Cyril Smiths papers and find the results very interesting. I'm still very curious to try and replicate the M.E.G and see what kind of results I can get from the nanoperm and metglas materials. It's my nature to want to see for myself. Thank you again.

Hi Gyula

This about the magnet on the MEG really is worring me because is possible that the magnet must to be conditioned like Floyd Sweet device but Hey, this magnet must to be Barium ferrite.

The problem here is power from the magnet is cancelled by the BEMF from the Actuator Coil, so if the magnet could self oscillate his own magnetic field then woul be procuces a big output.

Hi patmac,

I do not suppose that the magnet is conditioned in the MEG setup just like in the Sweet device. Did the Bearden team mention somewhere the neccessity of using barium ferrite magnets in their MEG?
(Yes, Floyd Sweet used BaFe magnets.)

I do not understand how you mean: The problem here is power from the magnet is cancelled by the BEMF from the Actuator Coil, ?

The flux from the Actuator coil must work either in favor or against the flux of the permanent magnet, in order to be able to steer it, it depends on input current polarity. So how you mean?
