This experimenter gets 6 times the power with the magnet between the coils:


The important point to note is that he is feeding A.C. current into the primary and the magnet is fixed to the stator!

                  Neo magnet attached Siamese "E" core's and twin primaries.

The challenge is to get 6 times the power from two microwave transformers with Neo magnets attached, through their 1 to 1 primaries in tandem powered by an A.C. current like Tinman succeeds at with his shaded pole motor stators.


He's only powering the coil with 4 A.C. volts!

Viewing the OzSolar-Power vid I came to the Raselli1 vids and some in there is refreshing !
About his core question : it is the cause why metglas/permalloys are used !
Thanks !

The transformer stator material is very high perm already. The percentage improvement with Metglass is not enough to justify the cost of the higher perm, but so what?

But I hope that you also read right the " before/after"  input/output Volt ratio : V to mV  !
To write about " power amplification" we need to know the power defining parameters ,before/after changes !

And for the OzSolarPower-experimenter core saturation is his CONCERN  !

Publicated papers related permanent magnets use in transformer core ,as help :

Sanshiro Ogino : without " basic factor" 0,3=30% efficiency with "basic factor" 1,0 = 100%

Keiichiro Asaoka   transformer core with airgap 1/40     airgap ovebridged by pm 1/1

The OzSolarPower " voltage amplifier"  I would compare with the old experiment results with now 50 years availability from the bolivian inventor Carlos Subieta-Garron.

The Raselli1 vids show the core/coil behaviour which are helpfull to to see the different effects related permanent magnet and electromagnet use in transformer core/-s !
To see the effects and thinking about "on/off"- switching ,flip-flop process !
