Ferrite toroid JT & magnet.

And I believe they can't.

The magnet changes the permeability of the core. This is a known effect that actually was at the root of Steorn's Orbo pulse motor of the third type (core effect). The effect can be very dramatic in a pulse motor. On a JT type oscillator the magnet changes the frequency of the oscillation, due to the permeability change in the core. Essentially the external magnetic field drives the core closer to saturation. This can help or hurt, depending on the material, the oscillation, and the worker's goal. However, you get out what you put in, minus losses.

By a strange coincidence, I too have been using a "reversed" transistor (collector and emitter swapped in the circuit) lately in my little JTs. Not all cores will work with the 2n3904-type reversed but some do and at much reduced current but still bright LED light. I haven't yet dug out any of my stash of 2n3055 transistors to try them yet. Right now I am thinking of a two-mosfet JT with the light output coming from a secondary winding under the center-tapped primary, similar to what I showed in my last JT video but with more turns on the secondary and a royer-type oscillator on the primary. I don't know if it will be as efficient as the simple JTs, probably not, since the mosfets will dissipate some power, but it will be interesting to try.

@TinselKoala,

I'm delighted that you chose to contribute to the thread. I understand that it's unfair for me to ask others to perform experiments for me, but again, it would be very simple for Lasersaber or Scratchrobo to test for OU the way I outlined. Short of that; Stoern's Orbo led to very exciting new discoveries, and both you and Jean Louis Naudin stand out as two of our foremost experimenters. My question to you is: What do you think of Nicoli Zaev's work and JL Naudin's well documented claim that his 2Sgen "6" has a COP of 13.7?

Although the laser saber ver3 seems to power a halogen lamp it is running a 12 volt battery pack . I can also run a 60 watt bulb from a tiny inverter with a 12 volts battery pack.. I am just wondering what the current draw is .

I am wonder so bad that i ordered that ferrite rod . it cost 29.00 dollars ., not the 2 he said . i used his exact link .
I will replicate it using the same wire ,same transistor same core and give you my results .

Mopozco has a cover video of his Transistor Oscillated Air Core Inductor demonstrating a COP of > 3:

Air has a dielectric constant or relative permativity just like ferrite. "The relative permittivity of a material under given conditions reflects the extent to which it concentrates electrostatic lines of flux." The same principles of quantum reguaging do work to generate power in Mopozco's Darlington pair air core overunity TROS inductor as they do to generate excess power in JLN's  2Sgen "6" Metglass core. Air molecules are staticly suspended inside Mopozco's inductor core, and magnatized there. The air molecule atom's electrons absorb ambient heat to do work on the copper windings as the electrons realign after the field is deformed by the electromagnetic pulse. Eccentric electrons break free as a proximate consequence, and account for the excess power. The ferrite material undergoes a mass reduction in moles of electrons and wears thin over time like copper windings in a generator. The air core of course can't ever wear out due to convection exchange, although the COP will remain lower compared to the higher permativity dielectric element cores like Barium Titanate etc.
