Lenz's law can be violated.

the ferrite rod can be biased with a permanent magnet, not a problem.

if this is true - and you can stimulate spontaneous oscillation in the resonant LC - then this would be a very simple & elegant proof that static PMs are inherently capable of doing work!

also - looks to me like this could contribute to an explanation for the operation of (at least 1 of?) the Coler device(s)!


Negative Differential Resistance (eg. reverse biased 2N2222A [no base connex] into cap) has always been a tantalising step away from free energy - due to the input energy required to provide the DC offset

but using a PM to provide the bias-offset energy in your arrangement above would seem to overcome the usual shortcoming of the 'Differential' characteristic

very cool !!

@ wayne

In my derivations I usually do a few step at a time,  are you familiar with the chain rule?       du/dt  = (du/dH) * (dH/dt)     I use it right after the product rule, and then I factor out a dH/dt.

@EM
The chain rule is not a problem..  don't get how you expanded the µ to have a "+" instead of a product in eq. 2 since µ= µoµr  ( http://en.wikipedia.org/wiki/Permeability_(electromagnetism) ).

eq 1: V = - N d phi/ dt  = -N d[ A * µ * H]/dt
eq. 2 :V = - N * A * µo * (dH/dt) * [ H * (dµr/dH)   +   Âµr ]

Please give attentention. The use of reverse silicon transistor was invented
from me, and published to elecronic paper elektuur, nederland (Bob van der Horst).
Years after.  Us Magazins habe take this  to create some more application from this.

No ONE habe understand why this device work, (My company was working over years to test, an selectimg semiconductors to industrial parameters ) so i find this.

IT is NOT an negative resistance !!. 
The working is (only near ny) an Tunnel-Diode, but the
characteristics are exactly the sam as for trigger diodes  usual 1ß to 50 volt type avaiable , or as little neons (100volts) as used in timing-base circuits in oszilloscopes
sins over 70 years).

alll this devices can used "to simuate" negative resitance. BUT it isnt.
better charteristics you can find from lamda diodes.

made from 2 fets
OR (!)
1 transistor and 1 FET.

hi Gustav

kudos to you for inventing the reverse silicon transistor oscillator!

please note that i mentioned "Negative Differential Resistance" - not true 'negative resistance'

all the best

I disagree that this would show proof that PM's can do work.

However, I would be interested to hear your explanation as to why you think this is so?
