Where the OVERUNITY using INDUCTION COILS comes from (eg Joule Thief)

[pfrattali]

It's so simple. There's nothing magical about it. There's no 'zero point energy from the vacuum' that you tap into. That's some
'woo woo' explanation.

Let me explain:

Faraday's Law states:
"The magnitude of the induced EMF in a conductor is directly proportional the rate of change of magnetic flux through the conductor."

Read this over and over and over until it hits you. The 'conductor' is a simple wire or a coil of wire. EMF is basically current.


The main process of how we get electricity into our homes is using generators. A generator, to put it basically, is magnetic flux lines
moving across coils. The magnet moves and coils are stationary, or visa versa; the coils move and the magnets are stationary. Either way the common process is magnetic flux lines cutting through coils, thus induction of current. The electrons in the copper wire of the coil are moved, excited, whatever you want to call it, and produce current.

Now, you can say the same for an electromagnet. By inducing a current into an electromagnet (a coil wound around an iron core), you produce a magnetic field similar to a permanent magnet. That magnetic field has flux lines just like a permanent magnet. The full size of the magnetic field does not appear instantly as you apply current to the coil. Picture blowing up a balloon. The edge of the balloon represents one of the flux lines. As you blow up the balloon, the edge of the ballo0n moves outward from within. Thus, the same way you put current into a coil, the flux lines created when the current produces an electromagnet expand outward and you have moving flux lines. Remember, the key to getting electricity is flux lines cutting through coil.  If you understand how Alternating Current through a transformer works, you will easier understand this.

Now, one step further. If you apply and remove current to the electromagnet at high speed using pulsed DC current oscillation, guess what you get? Read Faraday's Law above, again.  A high "rate of change of magnetic flux through the conductor."

"The magnitude of the induced EMF in a conductor is directly proportional the rate of change of magnetic flux through the conductor."

In other words, the faster you move those flux lines through coils, the higher the magnitude of induced Electromotive Force you get!

If you look at some of these Joule Thief circuits, you can get oscillations of 20,000 Hertz using a transistor and partnered coils. By pulsing DC current to one of the coils, you get a transformer like action with the other coil, inducing higher voltages and possibly higher amperage depending on how the coils are wound in relation to one another. At that frequency (20,000 Hz), imagine the speed of flux lines expanding and collapsing when you apply and remove current to the 'electromagnet'. Do you get the picture?

Finally, compare the frequency you get from your grid electricity: 50 or 60 Hertz. The flux lines of the generator magnet from your electric company are moving from North pole to South Pole and back is 60 times per second.

20,000 Hertz is 333 times greater than 60 Hertz. Think about it.

You still didn't explained it ;-) In simple terms : energy comes from magnetic field, the frequency is only a way to tap more or tap faster.


Why it isn't easy ? Because of the reaction ;-)

It's like taking water with a sieve...

That's some 'woo woo' explanation.

I agree but your analysis is not much better.

EMF is basically current.

No, EMF is basically voltage

In other words, the faster you move those flux lines through coils, the higher the magnitude of induced Electromotive Force you get!

Yes, but higher EMF does not necessarily constitute higher energy.

The flux lines of the generator magnet from your electric company are moving from North pole to South Pole and back is 60 times per second.  20,000 Hertz is 333 times greater than 60 Hertz. Think about it.

So the induced EMF will be 333 times higher ...but how does that lead to overunity?
Voltage is not energy!

THE WOO WOO BIT IS THE STUFF THAT MOVES DOWN THE POWER LINE IS
WOO WOO IN ITSELF. SO A SO CALL GENERATOR IS NOT A GENERATOR ,
BECAUSE ENERGY CAN NOT BE GENERATED. SO THE WOO WOO MACHINE
IS AN ETHER PUMP.
