This test was carried out to see if it is actually the oscillating magnet that is creating most of the current flow in the secondary,or the field distorting the field of the primary.

I added a diode in series with the FG output and primary coil to chop the bottom half of the AC.
The schematic below--not sure of dot convention,or how the common ground between my FG and scope will affect the seen results--but they are clear.

The first scope shot is with out the magnetic oscillator in play,and the second scope shot is with the magnetic oscillator in play.
As we can see,it is the oscillating magnet that is inducing the bulk of the EMF across the secondary/resistor combo.

My next goal is to get the 1:1 transformer wound,and also to set up the laser timing to see where the magnet is in relation to the primaries current flow.

Excellent test.

Does loading the sec affect the primary with the magnet in play? Just wondering as it may play out differently if the primary and sec were not wound over each other, as in putting the sec on the other side of the magnet to isolate its affect on the pri.  If winding the sec over the pri and loading the sec further reduces the primary input, then it is good as is.

Thanks for all your time with this Brad.

Hi, can you further decrease the input by making a pulse instead of a sine wave?

Maybe the travel will not be enough?
Maybe a magnet on a wine glass lol
Sorry,couldnt resist that one.
Brad

Brad, but that is maybe the classe difference, this is a nice satire!

Tired, mine Grammar is ............

Maybe you're I stick and driven like you do, is perfect!

And 6 pcs more left beside the I stick, and also 6 pcs more Right beside your first I stick.

North-Poles on all 13 sticks UP, related to diameter, bit to close together, so magnets FIELDS bounce, figure from the eagle view is a non-triggered flat wave sinus moving, serpent?

The middle one I stick, is driven like done and the rest follows.

Bit like out of mine example: With the protective people surroundings from the BAD actor Royal-BBC, when they follow resonance, than let them also help to drive 13 coils above the N or South pole.

Hi Diegra

Very nice video!!     Thanks for showing.      Nice place to work also.

modern speakers are moving coil type over stationary core/magnet,
previous speakers were moving armature like shown in above pic

celestion , moving iron balanced armature patent  : #230,552 = 1925 ,  #245,704 = 1926

Well it's throw out week around our area,and i managed to pick up 3 more smart drive washing machines.
Now have all the copper wire i need for up and coming experiments

Im here at lunch break and adjusting positioning of the coils.  Still more positions to fiddle with, but Im finding it to be getting better as I go. The 2 coils are both 4ohm.

Im getting to where it is exceeding expectations between the in and the out.  If it were just the 2 coils face to face, I would expect less voltage from the pickup coil with simple induction. Very inefficient coupling. And even if the coupling were very good, I would expect only as much voltage on the pickup/secondary as I put in the primary drive coil. But here the pickup is kicking butt.  No loads yet. But I want to see how far I can get with this to see how much more voltage I can get out of the pickup vs the drive voltage. So far, 2 identical coils with just straight AC input, we are seeing it as a step up voltage converter.  I am very happy with that.

One more thing. The input trace peak reading is a bit high due to spikes on the amp ch.  So the real sine peak is a bit lower than that. I calculated the input power based on that peak measurement with the spikes. So the input should be a bit lower than 40mw with a clean input. 

Once we get some good base measurements here with this setup, then we rebuild for higher freq which will increase eff even more, as has already been confirmed to do so.
