Re: About Ken's MEG switching model
- Camelazur, I'm glad to see someone is analyzing my stuff pretty
intensively. At first glance I noticed that your revised diagrams
show a meg state at t'2 (bottom left hand side) with all the magnet's
flux (1.2T) switched to the right side. This is inconsistant with the
diagrams above at t'2 which show that both inputs are zero and both
outputs are at a static magnetic flux of 0.6T. And that would also go
for the meg state at t'3 (bottom right hand side).
Your right about how the L3 and L4 wave diagrams should show a static
0.6T dotted line in the middle, I did this in my Meg state diagrams
I'll explain why I made this conclusion:
"When one input coil is turned on it forces all the flux to the
opposite side. For a small change in Flux applied to the input, A
larger change in Flux is available at the output."
If L1 (left input coil) changes from 0 to 0.6 T, then it will cancel
out the static B-field on the left hand side of the core (which is
0.6T) to zero. Well where does that 0.6T go, it can't just disappear.
The only place that it can go is to the right side of the core to
fill it up to 1.2T (but only a change of 0.6T on the right side). So
what just happened is the left side Changed from 0 to 0.6 T and the
right side changed from 0.6T to 1.2T. So for an input change of 0.6T
on the core, the left output coil sees a change of 0.6T and the right
out put coil sees a change of 0.6 T. Total input dB is 0.6 T, total
output dB is 1.2T.
It may seem that only half of the magnet's flux is being switched,
and that is true, only 0.6T of the magnet's flux is being switched.
But when you subtract 0.6T from highly permeable sheet steel the
magnetic atomic poles of the steel are being changed, picture them as
little magnets. And they generate their own B field as the B field is
being subtracted from it. So as the input is switched off and the
magnet returns to it's quiescent state and you attach a load to the
ouput coils the energy that is going into the load would really be
coming from the core itself and not the magnet. The magnet acts as a
catalyst to the magnetic poles in the core.
