Hi,

I'll take a wild guess that your coil did not have enough current
going through them to overcome the magnet.

I think its great that you and others are at least trying. I would
say that IMHO the MEG is extremely reliant upon the high permeable
properties of the core. I've seen people selling their metglas cores.
Perhaps you could find one really cheap.

Also, I think the exact current signals are extremely sensitive in the
MEG. Perhaps if the current signals are not close enough then it
won't work.

For anyone who's had a little success with the MEG, but who cannot get
it run continuously ... I would suggest, as an experiment, that they
try heating the core to various different degrees. Look at the
metglas core specs and find the curie temperature. Try keeping the
core to a high enough temperature where the core is still efficient.
If your MEG only works at a specific temperature then that could be a
big hint.

My 2 cents ;)
